What Are Messier Objects?
During the 18th century, astronomer and comet hunter Charles Messier wanted to distinguish the ‘faint fuzzies’ he observed from any potential new comets. As a result, Messier cataloged 110 objects in the night sky, ranging from star clusters to galaxies to nebulae. These items are designated by the letter ‘M’ and a number. For example, the Orion Nebula is Messier 42 or M42, and the Pleiades are Messier 45 or M45. These are among the brightest ‘faint fuzzies’ we can see with modest backyard telescopes and some even with our eyes.
Stargazers can catalog these items on evenings closest to the new moon. Some even go as far as having “Messier Marathons,” setting up their telescopes and binoculars in the darkest skies available to them, from sundown to sunrise, to catch as many as possible. Here are some items to look for this season:
M44 in Cancer and M65 and 66 in Leo can be seen high in the evening sky 60 minutes after sunset. Stellarium Web Messier 44 in Cancer: The Beehive Cluster, also known as Praesepe, is an open star cluster in the heart of the Cancer constellation. Use Pollux in Gemini and Regulus in Leo as guide stars. A pair of binoculars is enough to view this and other open star clusters. If you have a telescope handy, pay a visit two of the three galaxies that form the Leo Triplet – M65 and M66. These items can be seen one hour after sunset in dark skies.
Locate M3 and M87 rising in the east after midnight. Stellarium Web Messier 3 Canes Venatici: M3 is a globular cluster of 500,000 stars. Through a telescope, this object looks like a fuzzy sparkly ball. You can resolve this cluster in an 8-inch telescope in moderate dark skies. You can find this star cluster by using the star Arcturus in the Boötes constellation as a guide.
Messier 87 in Virgo: Located just outside of Markarian’s Chain, M87 is an elliptical galaxy that can be spotted during the late evening hours. While it is not possible to view the supermassive black hole at the core of this galaxy, you can see M87 and several other Messier-labeled galaxies in the Virgo Cluster using a medium-sized telescope.
Locate M76 and M31 setting in the west, 60 minutes after sunset. Stellarium Web Plan Ahead
When gearing up for a long stargazing session, there are several things to remember, such as equipment, location, and provisions:
Do you have enough layers to be outdoors for several hours? You would be surprised how cold it can get when sitting or standing still behind a telescope! Are your batteries fully charged? If your telescope runs on power, be sure to charge everything before you leave home and pack any additional batteries for your cell phone. Most people use their mobile devices for astronomy apps, so their batteries may deplete faster. Cold weather can also impact battery life. Determine the apparent magnitude of what you are trying to see and the limiting magnitude of your night sky. You can learn more about apparent and limiting magnitudes with our Check Your Sky Quality with Orion article. When choosing a location to observe from, select an area you are familiar with and bring some friends! You can also connect with your local astronomy club to see if they are hosting any Messier Marathons. It’s always great to share the stars! You can see all 110 items and their locations with NASA’s Explore the Night Sky interactive map and the Hubble Messier Catalog, objects that have been imaged by the Hubble Space Telescope.

The National Society of Professional Engineers recently named Debbie Korth, Orion deputy program manager at Johnson Space Center, as NASA’s 2025 Engineer of the Year. Korth was recognized during an award ceremony at the National Press Club in Washington, D.C., on Feb. 21, alongside honorees from 17 other federal agencies. The annual awards program honors the impactful contributions of federal engineers and their commitment to public service.
Debbie Korth received the NASA 2025 Engineer of the Year Award from the National Society of Professional Engineers at the National Press Club in Washington, D.C. Image courtesy of Debbie Korth Korth said she was shocked to receive the award. “At NASA there are so many brilliant, talented engineers who I get to work with every day who are so specialized and know so much about a certain area,” she said. “It was very surprising, but very appreciated.”
Korth has dedicated more than 30 years of her career to NASA, supporting human spaceflight development, integration, and operations across the Space Shuttle, International Space Station, and Orion Programs. Her earliest roles involved extravehicular and mission operations planning, as well as managing spaceflight hardware for shuttle missions and space station crews. Working on hardware such as the Crew Health Care System in the early days of space station planning and development was a unique experience for Korth.
After spending significant time in Russia collaborating with Russian counterparts to integrate equipment such as a treadmill, cycle ergometer, and blood pressure monitor into their module, Korth recalled, “When we finally got that all delivered and integrated, it was a huge step because we had to have all of that on board before we could put crew members on the station for the first time. I remember feeling a huge sense of accomplishment and happiness that we were able to work through this international partnership and forge those relationships to get that hardware integrated.”
Korth transitioned to the Orion Program in 2008 and has since served in a variety of leadership roles. In her current role, Korth assists the program manager in the design, development, testing, verification, and certification of Orion, NASA’s next-generation, human-rated spacecraft for Artemis missions. The spacecraft’s first flight test around the Moon during the Artemis I mission was a standout experience for Korth and a major accomplishment for the Orion team.
“It was a long mission and every day we were learning more and more about the spacecraft and pushing boundaries,” she said. “We really wrung out some of the core systems – systems that were developed individually and for the first time we got to see them work together.”
Korth said that understanding how different systems interact with each other is what she loves most about engineering. “In systems engineering, you really look at how changes to and the performance of one system affects everything else,” she said. “I like looking across the entire spacecraft and saying, if I have to strengthen this structure to take some additional landing loads, that’s going to add mass to the vehicle, which means I have to look at my parachutes and the thermal protection system to make sure they can handle that increased load.”
The Orion team is working to achieve two major milestones in 2025 – delivery of the Artemis II Orion spacecraft to the Exploration Ground Systems team that will fuel and integrate Orion with its launch abort system at NASA’s Kennedy Space Center, and the spacecraft’s integration with the Space Launch System rocket, which is currently being stacked. These milestones will support the launch of the first crewed mission on NASA’s path to establishing a long-term presence at the Moon for science and exploration, with liftoff targeted no earlier than April 2026.
“It’s going to be a big year,” said Korth.

Preventing biofilm formation in space
Ashley Keeley, University of Idaho, holds an anti-bacterial coating sample.University of Idaho Student Payload Opportunity with Citizen Science Team Two anti-microbial coatings reduced formation of biofilms in microgravity and have potential for use in space. Controlling biofilms could help protect human health and prevent corrosion and degradation of equipment on future long-duration space missions.
Biofilms, communities of microorganisms that attach to a surface, can damage mechanical systems and present a risk of disease transmission. Bacteria Resistant Polymers in Space examined how microgravity affects polymer materials designed to prevent or reduce biofilm formation. Better anti-fouling coatings also could reduce disease transmission on Earth.
Evaluating organ changes in lunar gravity
Set up for the Mouse Epigenetics experiment aboard the International Space Station. NASA Researchers found different changes in gene expression and other responses to simulated lunar gravity levels in specific organs. This finding could help determine safe gravity thresholds and support development of ways to maintain skeletal and immune function on future space journeys.
Spaceflight can affect skeletal and immune system function, but the molecular mechanisms of these changes are not clear. Mouse Epigenetics, a JAXA (Japan Aerospace Exploration Agency) investigation, studied gene expression changes in mice that spent a month in space and in the DNA of their offspring. Results could help determine spaceflight’s long-term effects on genetic activity, including changes within individual organs and those that can be inherited later.
Performance report for cosmic ray observatory
The CALorimetric Electron Telescope instrument is visible on the far left of the space station’s Kibo laboratory module. JAXA (Japanese Aerospace Exploration Agency)/Norishige Kanai Researchers report on-orbit performance from the first 8 years of operation of the International Space Station’s cosmic ray observatory, CALET. The instrument has provided valuable data on cosmic ray, proton, and helium spectra; produced a gamma-ray sky map; observed gamma-ray bursts; and searched for gravitational wave counterparts and solar effects.
The JAXA CALorimetric Electron Telescope or CALET helps address questions such as the origin and acceleration of cosmic rays and the existence of dark matter and nearby cosmic-ray sources. The instrument also could help characterize risks from the radiation environment that humans and electronics experience in space.

Catch Mercury if you can, then stay up late for a total lunar eclipse, and learn the truth about the dark side of the Moon.
Skywatching Highlights
All Month – Planets Visibility:
Mercury: Speedy Mercury is visible beneath Venus for the first week and a half of March, for about 30 minutes each evening, as sunset fades. Venus: Venus hangs low in the west after sunset early in the month, but quickly drops lower as the days pass. After mid-March, it’s difficult to observe in the glow of fading sunlight. Mars: Find Mars high in the east following sunset, then setting around 3 a.m. Jupiter: Visible high in the west after dark, and setting about 1 a.m. Daily Highlights:
March 7-9 – Catch Mercury: Look for Mercury beginning about 30 minutes after sunset in the west, about 10 degrees above the horizon.
March 13-14 – Total Lunar Eclipse: The Moon becomes a crimson orb over a couple of hours on March 13th and into the 14th, depending on your time zone.
March 14 – Full moon
March 29 – New moon: This is when the dark side of the Moon faces toward Earth. The new moon appears close to the Sun in the sky, so it’s essentially invisible from the surface (except during solar eclipses).

What’s Up for March? A good time to catch Mercury, an eclipse approaches, and the dark side of the Moon.
March Planet Viewing
March begins with Venus still hanging out low in the west after sunset, but it quickly drops out of the sky – by mid-month it’s getting lost in the glare of sunset. Once it gets dark, you’ll find Jupiter and Mars high overhead, keeping you company through the evening. Mars sets a couple of hours after midnight this month, leaving the morning sky “planet free” for the first time in a year.
Sky chart showing Venus and Mercury after sunset in early March. NASA/JPL-Caltech March also has the best opportunity this year for trying to spot fast-moving Mercury if you’re in the Northern Hemisphere. It’s only visible for a few weeks at a time every 3 to 4 months. This is because the speedy planet orbits the Sun in just 88 days, so it quickly shifts its position in the sky from day to day. It’s always visible either just after sunset or just before sunrise. On March 7th through 9th, look for Mercury beginning about 30 minutes after sunset in the west, about 10 degrees above the horizon.
You’ll want to ensure your view isn’t blocked by trees, buildings, or other obstructions. Observing from a large, open field, or the shore of a lake or the seaside can be helpful. Spying Mercury isn’t always easy, but catching the fleet-footed planet is a worthy goal for any skywatcher.
Total Lunar Eclipse
This map shows where the Moon will be above the horizon during the March 13-14 total lunar eclipse. There’s a total lunar eclipse on the way this month, visible across the Americas. Lunar eclipses can be viewed from anywhere the Moon is above the horizon at the time. The show unfolds overnight on March 13th and into the 14th, depending on your time zone. Check the schedule for your area for precise timing.
Now, during a total lunar eclipse, we watch as the Moon passes through Earth’s shadow. It first appears to have a bite taken out of one side, but as maximum eclipse nears, the Moon transforms into a deep crimson orb. That red color comes from the ring of all the sunsets and sunrises you’d see encircling our planet if you were an astronaut on the lunar surface right then. Afterward, the eclipse plays out in reverse, with the red color fading, and the dark bite shrinking, until the Moon looks like its usual self again.
And here’s an interesting pattern: eclipses always arrive in pairs. A couple weeks before or after a total lunar eclipse, there’s always a solar eclipse. This time, it’s a partial solar eclipse that will be visible across Eastern Canada, Greenland, and Northern Europe.
The Dark Side of the Moon
The Moon has a dark side, but it may not be what you think. As it orbits around Earth each month, the Moon is also rotating (or spinning). So, while we always see the same face of the Moon, sunlight sweeps across the lunar surface every month as it rotates.
This means there’s no permanently “dark” side. The Moon’s dark side faces Earth when the Moon passes between our planet and the Sun each month. This is the moment when the Moon is said to be “new,” as in a fresh start for its changing phases.
The new moon is also located quite close the Sun in the sky, making it more or less invisible, unless there’s a solar eclipse.
Nights around the new moon phase provide excellent opportunities for observing the sky – especially if you’re using a telescope or doing astrophotography. Without moonlight washing out the sky, you can better see faint stars, nebulas, the Milky Way, and distant galaxies. So next time someone mentions the “dark side of the Moon,” you’ll know there’s more to the story – and you might even discover some deep-sky treasures while the Moon takes its monthly break.
