Each evening this month, enjoy a sweeping view of four bright planets at once. Also look for a close approach of Venus and Saturn, Mars occulted by the Moon, and meteors!
Skywatching Highlights
January 3 – Quadrantid meteor shower peaks: This is a moderate shower, usually delivering 20 to 30 meteors per hour under clear, dark skies at its peak. No interference from the Moon makes this year’s peak a better bet for meteor watching.
January 13 – Moon Occults Mars: For skywatchers in the continental U.S. and Eastern Canada, the Moon will appear to pass in front of Mars this evening. Times vary by location, so check your favorite skywatching app for details.
January 17-18 – Venus and Saturn conjunction: Over a couple of weeks, the two planets come within just a couple of finger widths’ distance apart in the sky (about 2 degrees). They’re at their closest on the 17th and 18th.
All month – Four planets Visible: In the first couple of hours after dark, you’ll find Venus and Saturn in the southwest, Jupiter high overhead, and Mars in the east. (Uranus and Neptune are there too, but a telescope is needed to see them.) Planets always appear a long a line on the sky to the “alignment” isn’t special. What’s less common is seeing four or five bright planets at once, which doesn’t happen every year. Is it a “planet parade”? This isn’t a technical term in astronomy, so call it what you wish!
All month – Mars at Opposition: The Red Planet is directly opposite the Sun from Earth and shines brightly all night. It’s in the east as night falls and in the southwest at dawn.

What’s Up for January?
Cue the planet parade, Saturn and Venus cross paths, Mars expresses its opposition, and the outlook for the Quadrantid meteors.
In January, you’ll have the opportunity to take in four bright planets in a single, sweeping view.
Sky chart showing the planetary lineup visible after dark in January 2025. NASA/JPL-Caltech All month after dark, you’ll find Venus and Saturn in the southwest for the first couple of hours, while Jupiter shines brightly high overhead, and Mars rises in the east. Uranus and Neptune are there too, technically, but they don’t appear as “bright planets.” These multi-planet viewing opportunities aren’t super rare, but they don’t happen every year, so it’s worth checking it out.
Now, these events are sometimes called “alignments” of the planets, and while it’s true that they will appear more or less along a line across the sky, that’s what planets always do. That line is called the ecliptic, and it represents the plane of the solar system in which the planets orbit around the Sun. This is, incidentally, why we sometimes observe planets appearing to approach closely to each other on the sky, as we view them along a line while they careen around the cosmic racetrack.
Sky chart showing Venus and Saturn appearing quite close together on Jan. 17 and 18, 2025. NASA/JPL-Caltech This is exactly what we’ll be seeing from Venus and Saturn as they head for a super close approach in mid-January. After the beginning of the month, they quickly get closer and closer each evening, appearing at their most cozy on the 17th and 18th before going their separate ways. Remember, they’re really hundreds of millions of miles apart in space, so when you observe them, you’re staring clear across the solar system!
Mars reaches “opposition” this month, which is when the planet lies directly on the opposite side of Earth from the Sun, forming a straight line. This is around the time when the planet is at its closest to Earth, making it appear at its biggest and brightest. For Mars, oppositions happen about every two years. This one won’t be the most spectacular ever, but it’s still closer than average, and provides a great opportunity to observe the nearby planet where NASA has five missions currently operating.
And on the 13th, the full Moon cozies up to Mars, appearing super close to the Red Planet that evening. Across the U.S. and Eastern Canada, the Moon will appear to pass in front of Mars over a couple of hours, as the pair rise into the eastern sky. Mars also will be the lone planet in the sky on January mornings. You’ll find it hanging out in the west in morning twilight.
The Quadrantid meteors peak in the early morning hours on January 3rd. Interference from moonlight won’t be a problem, as the Moon is a mere crescent and sets early in the night. The way to see the most meteors is to observe after midnight from clear, dark skies away from bright city lights, and let your eyes adapt to the dark. The meteor rate will be highest as dawn approaches, and you’ll see more meteors from rural locations than in the suburbs. Now, this is a shower best seen from the Northern Hemisphere, and observers in the Northwest and Pacific region will likely have the best viewing this year.
Here are the phases of the Moon for January:

President Carter, wife Rosalynn and daughter Amy are shown a scale model of the crawler that transported the total shuttle launch configuration to Pad 39 from the Vehicle Assembly Building by NASA’s Kennedy Space Center Director Lee Scherer in 1978.NASA The following is a statement from NASA Administrator Bill Nelson on Sunday’s passing of President Jimmy Carter:
“President Carter was the pinnacle of a public servant, dedicating his life to making our world a better place. He showed us each and every person has the power to make a difference. From providing for those in need, protecting the environment, and championing civil and human rights, President Carter was a good man who always strove to do what was right. He embodied the very best of humanity and his life and legacy are an example to the United States and the world.
“NASA’s Voyager 1, the most distant human-made object from Earth, carries a message from President Carter that captures his core goodness and grace:
“’If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts, and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problems we face, to join a community of galactic civilizations. This record represents our hope and our determination, and our good will in a vast and awesome universe.’
“President Carter understood an important truth: that we find common ground when we look to the stars. His words will forever belong to the heavens, and his legacy has forever bettered our country – and our Earth. The NASA family and I are keeping the Carter family close in our thoughts. May President Carter rest in peace.”

NASA has taken a big step forward in how engineers will assemble and stack future SLS (Space Launch System) rockets for Artemis Moon missions inside the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida.
The VAB’s High Bay 2 has been outfitted with new tooling to facilitate the vertical integration of the SLS core stage. That progress was on full display in mid-December when teams suspended the fully assembled core stage 225 feet in the air inside the high bay to complete vertical work before it is stacked on mobile launcher 1, allowing teams to continue solid rocket booster stacking simultaneously inside High Bay 3 for Artemis II.
The fully assembled SLS (Space Launch System) core stage for the Artemis II test flight is suspended 225 feet in the air inside the newly renovated High Bay 2 at Kennedy’s Vehicle Assembly Building. The core stage was lifted to enable engineers to complete work before it is stacked on mobile launcher 1 with other rocket elements. With the move to High Bay 2, technicians now have 360-degree tip to tail access to the core stage, both internally and externally.NASA With the move to High Bay 2, technicians with NASA and Boeing now have 360-degree tip to tail access to the core stage, both internally and externally. Michigan-based supplier Futuramic Tool and Engineering led the design and build of the Core Stage Vertical Integration Center tool that will hold the core stage in a vertical position.
“High Bay 2 tooling was originally scheduled to be complete for Artemis III. We had an opportunity to get it done earlier and that will put us in a good posture to complete work earlier than planned prior to moving the core stage for Artemis II into the full integrated stack over into in High Bay 3,” said Chad Bryant, deputy manager of the NASA SLS Stages Office. “This gives us an opportunity to go in and learn how to rotate, lift, and move the core stage into the high bay.”
This move also doubles the footprint of useable space within the VAB, giving engineers access to both High Bay 2 and High Bay 3 simultaneously, while also freeing up space at NASA’s Michoud Assembly Facility in New Orleans to continue work on the individual elements for future SLS core stages.
High Bay 2 has a long history of supporting NASA exploration programs: during Apollo, High Bay 2, one of four high bays inside the VAB, was used to stack the Saturn V rocket. During the Space Shuttle Program, the high bay was used for external tank checkout and storage and as an extra storage area for the shuttle.
Under the new assembly model beginning with Artemis III, all the major structures for the SLS core stage will continue to be fully produced and manufactured at NASA Michoud. Upon completion of manufacturing and thermal protection system application, the engine section will be shipped to Kennedy for final outfitting.
The 212-foot-tall SLS (Space Launch System) core stage for NASA Artemis II is seen being moved from a horizontal position to a vertical position in High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. With the move to High Bay 2, NASA and Boeing technicians now have 360-degree access to the core stage both internally and externally. (NASA) “Core stage 3 marks a significant change in the way we build core stages,” said Steve Wofford, manager of the SLS Stages Office. “The vertical capability in High Bay 2 allows us to perform parallel processing from the top to bottom of the stage. It’s a much more efficient way to build core stages. This new capability will streamline final production efforts, allowing our team to have 360-degree access to the stage, both internally and externally.”
The fully assembled core stage for Artemis II arrived July 23, 2024, at Kennedy, where it remained horizontal inside the VAB transfer aisle until its recent lift into the newly outfitted high bay.
Teams at NASA Michoud are outfitting the remaining core stage elements for Artemis III and preparing to horizontally join them. The four RS-25 engines for the Artemis III mission are complete at NASA’s Stennis Space Center in Bay St. Louis, Mississippi, and will be transported to NASA Kennedy in 2025. Major core stage and exploration upper stage structures are in work at NASA Michoud for Artemis IV and beyond.
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
