Newly Selected Citizen Science Proposals: A Peek at What’s Next
Last year, the NASA citizen science community saw a prize from the White House and two prizes from professional societies: one from the Division of Planetary Sciences and one from the American Astronomical Society. Our teams published two papers in the prestigious journal, Nature, one on a planetary crash and one about a distant world that seems to have auroras. 2024 was a year of 5000 comets, two solar eclipses and plenty of broken records.
But we’re not stopping to rest on our laurels. In 2024, NASA selected 25 new citizen science proposals for funding that will lead to new projects and new results to look forward to in 2025 and beyond. Here’s a roundup of those selections and the principal investigators (PIs) of each team—a sneak peek at what’s coming next in NASA citizen science! Note that these investigations are research grants–some of them will result in new opportunities for the public, others will use results from earlier citizen science projects or develop new tools.

The CSSFP aims to support scientists and other experts to develop citizen science projects and to expand the pool of scientists who use citizen science techniques in their science investigations. Four divisions of NASA’s Science Mission Directorate are participating in the CSSFP: the Astrophysics Division, the Biological and Physical Sciences Division, the Heliophysics Division, and the Planetary Science Division. Nine new investigations were recently selected through this program:

Skywatching Home Skywatching The Next Full Moon is the Wolf… Skywatching Home What’s Up Eclipses Explore the Night Sky Night Sky Network More Tips and Guides FAQ 27 Min Read The Next Full Moon is the Wolf Moon
The Moon sets over Homestead National Historic Park in Nebraska. Credits:
National Park Service/Homestead The next full Moon is the Wolf Moon; the Ice or Old Moon; the Moon after Yule; the start of Prayag Kumbh Mela; Shakambhari Purnima; Paush Purnima; the Thiruvathira, Thiruvathirai, or Arudhra Darisanam festival Moon; and Duruthu Poya.
The phases of the Moon for January 2025. NASA/JPL-Caltech The next full Moon will be Monday evening, Jan. 13, 2025, appearing opposite the Sun (in Earth-based longitude) at 5:27 p.m. EST. This will be Tuesday from the South Africa and Eastern European time zones eastward across the remainder of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning. On the night of the full Moon, for most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of the planet Mars.
The Maine Farmers’ Almanac began publishing Native American names for full Moons in the 1930s. Over time these names have become widely known and used. According to this almanac, as the full Moon in January this is the Wolf Moon, from the packs of wolves heard howling outside the villages amid the cold and deep snows of winter.
European names for this Moon include the Ice Moon, the Old Moon, and (as the full Moon after the winter solstice) the Moon after Yule. Yule was a three to 12-day festival near the winter solstice in pre-Christian Europe. In the tenth century King Haakon I associated Yule with Christmas as part of the Christianization of Norway, and this association spread throughout Europe. The exact timing of this pre-Christian celebration is unclear. Some sources now associate Yule with the 12 days of Christmas, so that the Moon after Yule is after Twelfth Night on January 6. Other sources suggest that Yule is an old name for the month of January, so the Moon after Yule is in February. In the absence of more reliable historic information, I’m going with the full Moon after the winter solstice as the Moon after Yule.
This full Moon corresponds with the start of the 44-day festival Prayag Kumbh Mela, also known as Maha Kumbh. This Hindu pilgrimage and festival is held every 12 years in the Indian city of Prayagraj at the confluence of three rivers, the Ganges, the Yamuna, and the mythical Sarasvati. It is expected to draw around 400 million visitors. Similar Kumbh celebrations are held approximately every 12 years at the convergence of three rivers in three other Indian cities, Nashik (upcoming in 2027), Ujjain (in 2028), and Haridwar (in 2033).
In the Hindu calendar, this full Moon is Shakambhari Purnima, the last day in the 8-day Shakambari Navratri holiday that celebrates the goddess Shakambhari. In the Purnimanta tradition that ends months on the full Moon day, this full Moon is Paush Purnima, the last day of the Hindu month of Paush. The day after Paush Purnima is the start of the month of Magha, a period of austerity. Bathing in the holy waters of India is an important activity for both Shakambari Navratri and Magha.
This full Moon corresponds with the Thiruvathira, Thiruvathirai, or Arudhra Darisanam festival, celebrated by Hindus in the Indian states of Kerala and Tamil Nadu.
For the Buddhists of Sri Lanka, this is Duruthu Poya, which commemorates Siddhartha Gautama Buddha’s first visit to Sri Lanka.
In many lunar and lunisolar calendars the months change with the new Moon and full Moons fall in the middle of the lunar month. This full Moon is in the middle of the 12th and final month of the Chinese Year of the Rabbit. The new Moon on January 29 will be Chinese New Year, the start of the Year of the Snake. This full Moon is in the middle of Tevet in the Hebrew calendar and Rajab, the seventh month of the Islamic calendar. Rajab is one of the four sacred months in which warfare and fighting are forbidden.
As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon. Take care in the cold weather and take advantage of these early sunsets to enjoy and share the wonders of the night sky. And avoid starting any wars.
Here are the other celestial events between now and the full Moon after next, with times and angles based on the location of NASA Headquarters in Washington, D.C.:
As winter continues in the Northern Hemisphere, the daily periods of sunlight continue to lengthen. Our 24-hour clock is based on the average length of a day with the solar days near the solstices longer than those near the equinoxes. For Washington, D.C. and similar latitudes (I’ve not checked for other areas) the latest sunrise of the year (ignoring Daylight Saving Time) occurred on January 4. Monday, January 13 (the day of the full Moon), morning twilight will begin at 6:24 a.m. EST, sunrise will be at 7:26 a.m., solar noon will be at 12:17 p.m. when the Sun will reach its maximum altitude of 29.8 degrees, sunset will be at 5:08 p.m., and evening twilight will end at 6:11 p.m. By Wednesday, February 12 (the day of the full Moon after next), morning twilight will begin at 6:04 a.m., sunrise will be at 7:03 a.m., solar noon will be at 12:23 p.m. when the Sun will reach its maximum altitude of 37.7 degrees, sunset will be at 5:43 p.m., and evening twilight will end at 6:41 p.m.
This should be a good time for planet watching, especially with a backyard telescope. Venus, Jupiter, Mars, Saturn, and Uranus will all be in the evening sky. Brightest will be Venus, appearing in the southwestern sky. With a telescope you should be able to see it shift from half-full to a 29% illuminated crescent during this lunar cycle as it brightens and moves closer to the Earth.
Venus will reach its brightest for the year just after the full Moon after next. Second in brightness will be Jupiter in the eastern sky. With a telescope you should be able to see Jupiter’s four bright moons, Ganymede, Callisto, Europa, and Io, noticeably shifting positions in the course of an evening. Jupiter was at its closest and brightest in early December. Third in brightness will be Mars low in the east-northeastern sky. Mars will be at its closest and brightest for the year a few days after this full Moon. Fourth in brightness will be Saturn, appearing near Venus in the southwestern sky. With a telescope you should be able to see Saturn’s bright moon Titan and maybe its rings. The rings are appearing very thin and will be edge-on to the Earth in March 2025. We won’t get the “classic” view of Saturn showing off its rings until 2026. Saturn was at its closest and brightest in early September and will appear its closest to Venus (2.2 degrees apart) the evening of January 18. Fifth in brightness and technically bright enough to see without a telescope (if you are in a very dark location and your eyesight is better than mine) will be Uranus high in the southeastern sky. Uranus was at its closest and brightest in mid-November.
During this lunar cycle these planets will be rotating westward around the pole star Polaris (with Venus shifting more slowly) making them easier to see earlier in the evening, and friendlier for backyard stargazing, especially if you have young ones with earlier bedtimes.
Comets
As mentioned in my last posting, the sungrazing comet C/2024 G3 (ATLAS) will be passing very near the Sun on January 13. There is a chance that this comet will break up and vanish from view as it approaches the Sun, much as comet C/2024 S1 (ATLAS) did in October. In addition, its visual magnitude might not be bright enough to see in the daytime due to the glow of the nearby Sun. If it does not break up and is bright enough, Northern Hemisphere viewers will have the best viewing near its closest approach. For the Washington, D.C. area, it could be brightest the evening of January 12 before it sets on the southwestern horizon. You will need to find a distant object to block direct sunlight so you can safely look about 5 degrees to the upper right of the Sun. If the horizon is very clear, your best chance might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. Southern Hemisphere viewers will have the best viewing after closest approach, immediately after sunset from mid-January on (dimming each evening as it moves away from the Sun and the Earth). You may need binoculars or a telescope to see it, although comets are hard to predict.
Meteor Showers
Two minor meteor showers, the γ-Ursae Minorids (404 GUM) and α-Centaurids (102 ACE), will peak during this lunar cycle. The light of the waning Moon will interfere with the γ-Ursae Minorids peak on January 18. The α-Centaurids, only visible from the Southern Hemisphere, are expected to peak on February 8. In recent years the average peak has been 6 visible meteors per hour (under ideal conditions), although this shower showed bursts of 20 to 30 meteors per hour in 1974 and 1980. The best viewing conditions will likely be after the waxing gibbous Moon sets in the early mornings around the peak.
Evening Sky Highlights
On the evening of Monday, Jan. 13, 2025 (the evening of the full Moon), as twilight ends (at 6:11 p.m. EST), the rising Moon will be 13 degrees above the east-northeastern horizon with the bright planet Mars (the third brightest planet) 2 degrees to the lower left and the bright star Pollux (the brighter of the twin stars in the constellation Gemini, the twins) 3 degrees to the upper left of the Moon. The brightest planet visible will be Venus at 29 degrees above the southwestern horizon, with the planet Saturn (fourth brightest) 6 degrees to the upper left of Venus. The second brightest planet, Jupiter, will be 47 degrees above the eastern horizon. The bright star closest to overhead will be Capella at 50 degrees above the east-northeastern horizon. Capella is the 6th brightest star in our night sky and the brightest star in the constellation Auriga (the charioteer). Although we see Capella as a single star it is actually four stars (two pairs of stars orbiting each other). Capella is about 43 light years from us.
As this lunar cycle progresses, the planets and the background of stars will appear to rotate westward around the pole star Polaris each evening, with Venus initially shifting the other direction. Mars will be at its closest and brightest on January 15. Venus and Saturn will appear closest to each other on January 18. Mars and Pollux will appear nearest each other on January 22 and 23. Venus will appear at its highest above the horizon (as twilight ends) on January 27, after which it will start shifting toward the horizon again. Jupiter and Aldebaran will appear at their closest on January 31. The waxing Moon will pass by Saturn on January 31; Venus on February 1; the Pleiades star cluster on February 5; and Mars and Pollux on February 10.
By the evening of Wednesday, February 12 (the evening of the full Moon after next), as twilight ends (at 6:41 p.m. EST), the rising Moon will be 7 degrees above the east-northeastern horizon with the bright star Regulus 2 degrees to the right. The brightest planet in the sky will be Venus at 28 degrees above the west-southwestern horizon, appearing as a crescent through a telescope. Next in brightness will be Jupiter at 71 degrees above the south-southeastern horizon. Third in brightness will be Mars at 48 degrees above the eastern horizon. Saturn will be 11 degrees above the west-southwestern horizon. Uranus, on the edge of what is visible under extremely clear, dark skies, will be 68 degrees above the south-southwestern horizon. The bright star closest to overhead will still be Capella at 75 degrees above the northeastern horizon.
Also high in the sky will be the constellation Orion, easily identifiable because of the three stars that form Orion’s Belt. This time of year, we see many bright stars in the sky at evening twilight, with bright stars scattered from the south-southeast toward the northwest. We see more stars in this direction because we are looking toward the Local Arm of our home galaxy (also called the Orion Arm, Orion-Cygnus Arm, or Orion Bridge). This arm is about 3,500 light years across and 10,000 light years long. Some of the bright stars we see from this arm are the three stars of Orion’s Belt, as well as Rigel (860 light years from Earth), Betelgeuse (548 light years), Polaris (about 400 light years), and Deneb (about 2,600 light years).
Facing toward the south from the northern hemisphere, to the upper left of Orion’s Belt is the bright star Betelgeuse (be careful not to say this name three times). About the same distance to the lower right is the bright star Rigel. Orion’s belt appears to point down and to the left about seven belt lengths to the bright star Sirius, the brightest star in the night sky. Below Sirius is the bright star Adara. To the upper right of Orion’s Belt (at about the same distance from Orion as Sirius) is the bright star Aldebaran. Nearly overhead is the bright star Capella. To the left (east) of Betelgeuse is the bright star Procyon. The two stars above Procyon are Castor and Pollux, the twin stars of the constellation Gemini (Pollux is the brighter of the two). The bright star Regulus appears farther to the left (east) of Pollux near the eastern horizon. Very few places on the East Coast are dark enough to see the Milky Way (our home galaxy), but if you could see it, it would appear to stretch overhead from the southeast to the northwest. Since we are seeing our galaxy from the inside, the combined light from its 100 billion to 400 billion stars make it appear as a band surrounding the Earth.
Morning Sky Highlights
On the morning of Monday, Jan. 13, 2025 (the morning of the full Moon), as twilight begins (at 6:23 a.m. EST), the setting full Moon will be 11 degrees above the west-northwestern horizon. This will be the last morning the planet Mercury will rise before morning twilight begins, although it will be bright enough to see in the glow of dawn after it rises for another week or so. This will leave Mars at 18 degrees above the west-northwestern horizon as the only planet in the sky. The bright star appearing closest to overhead will be Arcturus at 69 degrees above the south-southeastern horizon. Arcturus is the brightest star in the constellation Boötes (the herdsman or plowman) and the 4th brightest star in our night sky. It is 36.7 light years from us. While it has about the same mass as our Sun, it is about 2.6 billion years older and has used up its core hydrogen, becoming a red giant 25 times the size and 170 times the brightness of our Sun. One way to identify Arcturus in the night sky is to start at the Big Dipper, then follow the arc of the dipper’s handle as it “arcs toward Arcturus.”
As this lunar cycle progresses Mars and the background of stars will appear to rotate westward around the pole star Polaris by about 1 degree each morning. The waning Moon will appear near Mars and Pollux on January 13 and 14, Regulus on January 16, Spica on January 21, Antares on January 24 and 25, and (rising after morning twilight begins) Mercury on January 28. January 22 will be the last morning the planet Mercury will be above the horizon 30 minutes before sunrise. Mars and Pollux will be near their closest to each other the morning of January 23. February 4 will be the last morning the planet Mars will be above the northwestern horizon as morning twilight begins. The waxing Moon will appear near Pollux on February 9 (setting before twilight begins) and 10.
By the morning of Wednesday, February 12 (the morning of the full Moon after next), as twilight begins (at 6:04 a.m. EST), the setting full Moon will be 13 degrees above the western horizon. No planets will appear in the sky. The bright star appearing closest to overhead will still be Arcturus at 65 degrees above the southeastern horizon.
Detailed Daily Guide
Here is a day-by-day listing of celestial events between now and the full Moon on Feb. 12, 2025. The times and angles are based on the location of NASA Headquarters in Washington, D.C., and some of these details may differ for where you are (I use parentheses to indicate times specific to the D.C. area). If your latitude is significantly different than 39 degrees north (and especially for my Southern Hemisphere readers), I recommend using an astronomy app set for your location or a star-watching guide from a local observatory, news outlet, or astronomy club.
Tuesday evening, January 7 At 7:07 p.m. EST, the Moon will be at perigee, its closest to the Earth for this orbit.
Thursday evening, January 9 The waxing gibbous Moon will pass in front of the Pleiades star cluster. This may be viewed best with binoculars, as the brightness of the Moon will make it hard to see the stars in this star cluster. As evening twilight ends at 6:07 p.m. EST, the Pleiades will appear 1 degree to the lower left of the full Moon. Over the next few hours, including as the Moon reaches its highest for the night at 8:37 p.m., the Moon will pass in front of the Pleiades, blocking many of these stars from view. By about midnight the Pleiades will appear about 1 degree below the Moon, and the Moon and the Pleiades will separate as Friday morning progresses.
Also on Thursday night, January 9, the planet Venus will reach its greatest angular separation from the Sun as seen from the Earth for this apparition (called greatest elongation). Because the angle between the line from the Sun to Venus and the line of the horizon changes with the seasons, the date when Venus and the Sun appear farthest apart as seen from Earth is not always the same as when it appears highest above the west-southwestern horizon as evening twilight ends, which occurs on January 27.
Friday evening, January 10 The bright planet Jupiter will appear near the waxing gibbous Moon. As evening twilight ends at 6:08 p.m. EST, Jupiter will be 5 degrees to the lower right. As the Moon reaches its highest for the night at 9:37 p.m., Jupiter will be 6 degrees below the Moon. The pair will continue to separate until Jupiter sets Saturday morning at 4:45 a.m.
Sunday afternoon, January 12 There is a slight chance that the sungrazing comet, C/2024 G3 (ATLAS) might be visible near the setting Sun. Most likely, this comet will not be bright enough to see in the daytime or will break up and vanish from view like comet C/2024 S1 (ATLAS) did in October. The odds are low, but if the sky is clear, find an object to block direct sunlight (the farther away the object the better) so you can safely look about 5 degrees to the upper right of the Sun. If the west-southwestern horizon is clear, your best chance might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. This will only be visible from the Northern Hemisphere. Southern Hemisphere viewers may be able to see this comet from mid-January on immediately after sunset (dimming each evening as it moves away from us).
Monday morning, January 13 This is the morning of the full Moon. It will be the last morning Mercury will rise before morning twilight begins, although it will be bright enough to see in the glow of dawn after it rises for another week or so.
The Moon will be full Monday evening at 5:27 p.m. EST. This will be on Tuesday from the South Africa and Eastern European time zones eastward across the rest of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning.
On Monday night the full Moon will appear near and pass in front of the bright planet Mars, with the bright star Pollux above the pair. As evening twilight ends at 6:11 p.m. EST, the three will form a triangle, with Mars 2 degrees to the lower left and Pollux 3 degrees to the upper left of the Moon. For most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of Mars. Times will vary for other locations, but for NASA Headquarters in Washington, D.C., Mars will vanish behind the bottom of the Moon at about 9:16 p.m. and reappear from behind the upper right of the Moon at about 10:31 p.m. By the time the Moon reaches its highest for the night early on Tuesday morning at 12:37 a.m., Mars will be 1 degree to the right of the Moon and Pollux 5 degrees to the upper right. As morning twilight begins at 6:23 a.m., Mars will be 4 degrees and Pollux 8 degrees to the lower right of the Moon.
Wednesday night January 15 The planet Mars will be at opposition, so called because it will be opposite the Earth from the Sun, effectively a “full” Mars. Near opposition Mars will be at its closest and brightest for the year. On Wednesday night, as evening twilight ends at 6:13 p.m. EST, Mars will be 14 degrees above the east-northeastern horizon. Mars will reach its highest in the sky early Thursday morning at 12:21 a.m., and will be 15 degrees above the west-northwestern horizon as morning twilight begins at 6:23 a.m. Only planets that orbit farther from the Sun than the Earth can be seen at opposition from the Earth.
Wednesday night into Thursday morning, January 15 to 16 The bright star Regulus will appear near the waning gibbous Moon. As Regulus rises on the east-northeastern horizon at 7:52 p.m. EST, it will be more than 8 degrees below the Moon. By the time the Moon reaches its highest for the night on Thursday morning at 2:17 a.m. Regulus will be 5.5 degrees to the lower left of the Moon. As morning twilight begins at 6:23 a.m. Regulus will be 4 degrees to the left of the Moon.
Saturday evening, January 18 Venus and Saturn will appear nearest to each other. As evening twilight ends at 6:15 p.m. EST, Venus will be 30 degrees above the southwestern horizon with Saturn 2.2 degrees to the lower left. Saturn will set first on the western horizon almost 3 hours later at 9:04 p.m.
Monday night, January 20 At 11:53 p.m. EST, the Moon will be at apogee, its farthest from the Earth for this orbit.
Tuesday morning, January 21 The bright star Spica will appear near the waning gibbous Moon. As the Moon rises on the east-southeastern horizon at 12:11 a.m. EST Spica will be 1 degree above the Moon. By the time the Moon reaches its highest for the night at 5:41 a.m., Spica will be 3.5 degrees to the upper right, with morning twilight beginning 40 minutes later at 6:21 a.m. For parts of Western Africa and the Atlantic Ocean the Moon will pass in front of Spica.
Tuesday afternoon, the waning Moon will appear half-full as it reaches its last quarter at 3:31 p.m. EST (when we can’t see it).
Wednesday morning, January 22 This will be the last morning Mercury will be above the horizon 30 minutes before sunrise, an approximation of the last morning it might be visible in the glow of dawn.
Throughout this lunar cycle, Mars and the bright star Pollux will appear near each other, with Wednesday night into Thursday morning and Thursday night into Friday morning (January 22, 23, and 24) the nights when they will be at their closest, 2.5 degrees apart. They will be up all night for both nights, with Mars at its highest on Wednesday night at 11:41 p.m. EST, and Thursday night at 11:36 p.m.
Friday morning, January 24 The bright star Antares will appear to the lower left of the waning crescent Moon. As Antares rises on the southeastern horizon at 3:54 a.m. EST, it will be 8 degrees from the Moon. By the time morning twilight begins less than 2.5 hours later at 6:19 a.m., Antares will be 6.5 degrees from the Moon. For part of the Indian Ocean the Moon will actually pass in front of Pollux.
Saturday morning, January 25 The Moon will have shifted to the other side of Antares. As the Moon rises at 4:20 a.m. EST, Antares will be 6 degrees to the upper right of the Moon. By the time morning twilight begins 2 hours later at 6:19 a.m., Antares will be 7 degrees from the Moon.
Monday evening, January 27 Venus will be at its highest above the west-southwestern horizon (31 degrees) as evening twilight ends at 6:25 p.m. EST, appearing as a 41% illuminated crescent through a telescope.
Wednesday morning, January 29 At 7:36 a.m. EST there will be a new Moon, when the Moon passes between the Earth and the Sun, and the Moon will not be visible from the Earth. The day of, or the day after, the New Moon marks the start of the new month for most lunisolar calendars. The first month of the Chinese calendar starts on Wednesday, January 29, making this Chinese New Year, the start of the Year of the Snake! Chinese New Year and related celebrations throughout much of Asia and in areas with significant Chinese populations celebrate the end of winter and start of spring. Traditional festivities start on the eve of Chinese New Year and continue until the Lantern Festival on the 15th day of the first lunar month.
Sundown on Wednesday, January 29 This marks the start of Shevat in the Hebrew calendar.
Sundown on Thursday, January 30 In the Islamic calendar, the months traditionally start with the first sighting of the waxing crescent Moon. Many Muslim communities now follow the Umm al-Qura Calendar of Saudi Arabia, which uses astronomical calculations to start months in a more predictable way. Using this calendar, sundown on Thursday, January 30, will probably mark the beginning of Shaʿbān, the eighth month of the Islamic year and the month before Ramadan.
Friday evening, January 31 Saturn will appear 4 degrees to the upper left of the waxing crescent Moon. The Moon will be 17 degrees above the west-southwestern horizon as evening twilight ends at 6:29 p.m. EST, and will set on the western horizon 99 minutes later at 8:08 p.m. For part of Asia the Moon will actually pass in front of Saturn.
Throughout this lunar cycle the bright star Aldebaran will appear below the bright planet Jupiter, with Friday, January 31 the evening they appear at their closest, about 5 degrees apart. As evening twilight ends at 6:29 p.m. EST, Jupiter will be 65 degrees above the southeastern horizon with Aldebaran to the lower right. Jupiter will reach its highest for the night, 73 degrees above the southern horizon at 8:01 p.m., with Aldebaran below Jupiter. As Aldebaran sets on the west-northwestern horizon almost 7 hours after that at 2:56 a.m. it will be to the lower left of the Moon.
Saturday evening, February 1 Venus will appear near the waxing crescent Moon. The Moon will be 30 degrees above the west-southwestern horizon as evening twilight ends at 6:30 p.m. EST, with Venus 2.5 degrees to the upper right. Venus will be 2.5 degrees to the lower right as it sets first on the western horizon 2.75 hours later at 9:15 p.m.
Saturday night, at 9:38 p.m. EST, the Moon will be at perigee, its closest to the Earth for this orbit.
Saturday also is Imbolc or Imbolg, and the next day (Sunday, February 2) is Candlemas or Groundhog’s Day. We currently divide the year into four seasons based upon the solstices and equinoxes, with spring starting on the vernal equinox. This approximates winter as the quarter of the year with the coldest temperatures. Much of pre-Christian northern Europe celebrated “cross-quarter days” halfway between the solstices and equinoxes, dividing the seasons on these days. Using this definition, winter was the quarter of the year with the shortest daily periods of daylight, and spring started on Imbolc (the middle of our winter).
The tradition in some European countries was to leave Christmas decorations up until February 1st, the eve of Candlemas, and it was considered bad luck to leave decorations up past this date. Robert Herrick (1591-1674) starts his poem “Ceremonies for Candlemas Eve” with “Down with the rosemary and bays, down with the mistletoe; Instead of holly, now up-raise the greener box (for show).”
We have a tradition in the United States that winter will end on Groundhog Day if the groundhog sees its shadow. If not, winter will last six weeks more (ending around the time of the spring equinox). Groundhog Day appears to tie back to European lore about whether or not badgers, wolves, or bears (instead of groundhogs) see their shadows. Many believe that these Groundhog Day and Candlemas traditions tie back to these earlier celebrations for the start of spring. It seems plausible to me that it was confusing to have two competing dates for the end of winter. Perhaps it was best to let a natural event such as an animal’s shadow decide which definition to use, rather than arguing with your neighbors for the next six weeks.
Tuesday morning, February 4 This will be the last morning Mars will be above the northwestern horizon as morning twilight begins.
Wednesday morning, February 5 The Moon will appear half-full as it reaches its first quarter at 3:02 a.m. EST (when we can’t see it).
Wednesday evening the waxing gibbous Moon will appear near the Pleiades star cluster. As evening twilight ends at 6:34 p.m. EST, this star cluster will be 5 degrees to the upper left of the Moon. The Pleiades will shift closer toward the Moon until the Moon sets on the west-northwestern horizon less than 8 hours later at 2:16 a.m. Some North American locations farther west will actually see the Moon pass in front of some of the stars in the Pleiades.
Sunday morning, February 9 Mars will appear to the upper left of the waxing gibbous Moon. In the early morning at about 2 a.m. EST, Mars will be 8 degrees from the Moon. By the time the Moon sets on the northwestern horizon at 5:58 a.m., Mars will have shifted to 6 degrees from the Moon. For parts of Asia and Northern Europe the Moon will pass in front of Mars.
Also Sunday morning, Mercury will be passing on the far side of the Sun as seen from the Earth, called superior conjunction. Because Mercury orbits inside of the orbit of Earth it will be shifting from the morning sky to the evening sky and will begin emerging from the glow of dusk on the west-southwestern horizon after about February 17 (depending upon viewing conditions).
Sunday evening into Monday morning, February 9 to 10 The waxing gibbous Moon will have shifted to the other side of Mars (having passed in front of Mars in the afternoon when we could not see them). As evening twilight ends at 6:38 p.m. EST, the Moon will be between Mars and the bright star Pollux, with Mars 3 degrees to the upper right and Pollux 3 degrees to the lower left. By the time the Moon reaches its highest for the night at 10:27 p.m., Mars will be 4.5 degrees to the right of the Moon and Pollux 2.5 degrees to the upper left of the Moon. Mars will set first on the northwestern horizon Monday morning at 5:44 a.m. just 22 minutes before morning twilight begins at 6:06 a.m.
Wednesday morning, February 12 The full Moon after next will be at 8:53 a.m. EST, with the bright star Regulus nearby. This will be on Thursday morning from Australian Central Time eastward to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Monday night into early Thursday evening.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Next Generation Lunar Retroreflector, or NGLR-1, is one of 10 payloads set to fly aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative in 2025. NGLR-1, outfitted with a retroreflector, will be delivered to the lunar surface to reflect very short laser pulses from Earth-based lunar laser ranging observatories. Photo courtesy Firefly Aerospace Apollo astronauts set up mirror arrays, or “retroreflectors,” on the Moon to accurately reflect laser light beamed at them from Earth with minimal scattering or diffusion. Retroreflectors are mirrors that reflect the incoming light back in the same incoming direction. Calculating the time required for the beams to bounce back allowed scientists to precisely measure the Moon’s shape and distance from Earth, both of which are directly affected by Earth’s gravitational pull. More than 50 years later, on the cusp of NASA’s crewed Artemis missions to the Moon, lunar research still leverages data from those Apollo-era retroreflectors.
As NASA prepares for the science and discoveries of the agency’s Artemis campaign, state-of-the-art retroreflector technology is expected to significantly expand our knowledge about Earth’s sole natural satellite, its geological processes, the properties of the lunar crust and the structure of lunar interior, and how the Earth-Moon system is changing over time. This technology will also allow high-precision tests of Einstein’s theory of gravity, or general relativity.
That’s the anticipated objective of an innovative science instrument called NGLR (Next Generation Lunar Retroreflector), one of 10 NASA payloads set to fly aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. NGLR-1 will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.
Developed by researchers at the University of Maryland in College Park, NGLR-1 will be delivered to the lunar surface, located on the Blue Ghost lander, to reflect very short laser pulses from Earth-based lunar laser ranging observatories, which could greatly improve on Apollo-era results with sub-millimeter-precision range measurements. If successful, its findings will expand humanity’s understanding of the Moon’s inner structure and support new investigations of astrophysics, cosmology, and lunar physics – including shifts in the Moon’s liquid core as it orbits Earth, which may cause seismic activity on the lunar surface.
“NASA has more than half a century of experience with retroreflectors, but NGLR-1 promises to deliver findings an order of magnitude more accurate than Apollo-era reflectors,” said Dennis Harris, who manages the NGLR payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
Deployment of the NGLR payload is just the first step, Harris noted. A second NGLR retroreflector, called the Artemis Lunar Laser Retroreflector (ALLR), is currently a candidate payload for flight on NASA’s Artemis III mission to the Moon and could be set up near the lunar south pole. A third is expected to be manifested on a future CLPS delivery to a non-polar location.
“Once all three retroreflectors are operating, they are expected to deliver unprecedented opportunities to learn more about the Moon and its relationship with Earth,” Harris said.
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

5 Min Read NASA’s Parker Solar Probe Makes History With Closest Pass to Sun
An artist’s concept showing Parker Solar Probe. Credits:
NASA/APL Operations teams have confirmed NASA’s mission to “touch” the Sun survived its record-breaking closest approach to the solar surface on Dec. 24, 2024.
Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, NASA’s Parker Solar Probe hurtled through the solar atmosphere at a blazing 430,000 miles per hour — faster than any human-made object has ever moved. A beacon tone received late on Dec. 26 confirmed the spacecraft had made it through the encounter safely and is operating normally.
This pass, the first of more to come at this distance, allows the spacecraft to conduct unrivaled scientific measurements with the potential to change our understanding of the Sun.
Flying this close to the Sun is a historic moment in humanity’s first mission to a star.

“Flying this close to the Sun is a historic moment in humanity’s first mission to a star,” said Nicky Fox, who leads the Science Mission Directorate at NASA Headquarters in Washington. “By studying the Sun up close, we can better understand its impacts throughout our solar system, including on the technology we use daily on Earth and in space, as well as learn about the workings of stars across the universe to aid in our search for habitable worlds beyond our home planet.”

Parker Solar Probe has spent the last six years setting up for this moment. Launched in 2018, the spacecraft used seven flybys of Venus to gravitationally direct it ever closer to the Sun. With its last Venus flyby on Nov. 6, 2024, the spacecraft reached its optimal orbit. This oval-shaped orbit brings the spacecraft an ideal distance from the Sun every three months — close enough to study our Sun’s mysterious processes but not too close to become overwhelmed by the Sun’s heat and damaging radiation. The spacecraft will remain in this orbit for the remainder of its primary mission.
“Parker Solar Probe is braving one of the most extreme environments in space and exceeding all expectations,” said Nour Rawafi, the project scientist for Parker Solar Probe at the Johns Hopkins Applied Physics Laboratory (APL), which designed, built, and operates the spacecraft from its campus in Laurel, Maryland. “This mission is ushering a new golden era of space exploration, bringing us closer than ever to unlocking the Sun’s deepest and most enduring mysteries.”
Close to the Sun, the spacecraft relies on a carbon foam shield to protect it from the extreme heat in the upper solar atmosphere called the corona, which can exceed 1 million degrees Fahrenheit. The shield was designed to reach temperatures of 2,600 degrees Fahrenheit — hot enough to melt steel — while keeping the instruments behind it shaded at a comfortable room temperature. In the hot but low-density corona, the spacecraft’s shield is expected to warm to 1,800 degrees Fahrenheit.
The spacecraft’s record close distance of 3.8 million miles may sound far, but on cosmic scales it’s incredibly close. If the solar system was scaled down with the distance between the Sun and Earth the length of a football field, Parker Solar Probe would be just four yards from the end zone — close enough to pass within the tenuous outer atmosphere of the Sun known as the corona. NASA/APL “It’s monumental to be able to get a spacecraft this close to the Sun,” said John Wirzburger, the Parker Solar Probe mission systems engineer at APL. “This is a challenge the space science community has wanted to tackle since 1958 and had spent decades advancing the technology to make it possible.”
By flying through the solar corona, Parker Solar Probe can take measurements that help scientists better understand how the region gets so hot, trace the origin of the solar wind (a constant flow of material escaping the Sun), and discover how energetic particles are accelerated to half the speed of light.
“The data is so important for the science community because it gives us another vantage point,” said Kelly Korreck, a program scientist at NASA Headquarters and heliophysicist who worked on one of the mission’s instruments. “By getting firsthand accounts of what’s happening in the solar atmosphere, Parker Solar Probe has revolutionized our understanding of the Sun.”
Previous passes have already aided scientists’ understanding of the Sun. When the spacecraft first passed into the solar atmosphere in 2021, it found the outer boundary of the corona is wrinkled with spikes and valleys, contrary to what was expected. Parker Solar Probe also pinpointed the origin of important zig-zag-shaped structures in the solar wind, called switchbacks, at the visible surface of the Sun — the photosphere.
Since that initial pass into the Sun, the spacecraft has been spending more time in the corona, where most of the critical physical processes occur.
This conceptual image shows Parker Solar Probe about to enter the solar corona. NASA/Johns Hopkins APL/Ben Smith “We now understand the solar wind and its acceleration away from the Sun,” said Adam Szabo, the Parker Solar Probe mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This close approach will give us more data to understand how it’s accelerated closer in.”
Parker Solar Probe has also made discoveries across the inner solar system. Observations showed how giant solar explosions called coronal mass ejections vacuum up dust as they sweep across the solar system, and other observations revealed unexpected findings about solar energetic particles. Flybys of Venus have documented the planet’s natural radio emissions from its atmosphere, as well as the first complete image of its orbital dust ring.
So far, the spacecraft has only transmitted that it’s safe, but soon it will be in a location that will allow it to downlink the data it collected on this latest solar pass.
The data that will come down from the spacecraft will be fresh information about a place that we, as humanity, have never been.
Joe Westlake
Heliophysics Division Director, NASA Headquarters
“The data that will come down from the spacecraft will be fresh information about a place that we, as humanity, have never been,” said Joe Westlake, the director of the Heliophysics Division at NASA Headquarters. “It’s an amazing accomplishment.”
The spacecraft’s next planned close solar passes come on March 22, 2025, and June 19, 2025.

On December 25, 2024, NASA's Stereo Lasco C3 satellite captured an extraordinary phenomenon near the sun. In a split second, the satellite's imaging was disrupted by what appeared to be a swarm of spherical objects hurtling through space at incredible speeds.
Speculation surrounds the event, with some suggesting it could be a meteor debris field. However, the unusual appearance of the objects has raised questions. Could debris naturally form into such perfectly round shapes, each featuring a dark center that resembles donut-shaped UFOs?
This event might be a natural occurrence, however, with all the recent strange sightings of unknown drones, UFOs, and orbs combined with predictions from several specialists that something significant might happen soon in the realm of the UFO phenomena, one might wonder if these mysterious spheres are connected to something larger on the horizon?
