A total lunar eclipse is coming 🌕 🌏 ☀️ In the early morning hours of March 3, 2026 (UTC), the full Moon will pass through Earth’s shadow, reddening the lunar surface. Here’s what you need to know: Credit: NASA’s Scientific Visualization Studio

This asteroid is a little… quirky. Shaped like a five-mile-long peanut 🥜 Wobbles like a top 🌪️ Encountered water, but lost it 💦 Published today, NASA’s Lucy mission reveals close-up imagery and data from its flyby of oddball asteroid Donaldjohanson. More:

Moon phases, but different. 🌖 🌒 Soon, humans will be on the far side of the Moon. From the Artemis II crew's POV, the Moon phase will be the opposite of what we see on Earth. Follow us for lunar science updates throughout the mission. Where will you view the full Moon from?

As it sped past Mars in March, Europa Clipper conducted a critical radar test that had been impossible to do on Earth. It went without a hitch, generating a detailed radargram of the Martian surface, which bodes well for exploring Jupiter's icy moon Europa

More about 16 Psyche, the asteroid that #MissionToPsyche will explore, one of the most intriguing targets in the main asteroid belt:

From the Moon, a lunar eclipse looks like a total solar eclipse, but it lasts a LOT longer. For NASA's Lunar Reconnaissance Orbiter, that means the team has to plan carefully for the 4 hours that the spacecraft — and its solar panels — will be in the dark and the cold. 🌑🛰 1/3

🧵3/4 A wider view of the same event. From SOHO’s wide coronagraph, we see a clearer view of the dust cloud emerging after the flyby. It looks like comet MAPS dove straight into the Sun… but another spacecraft’s view tells a different story.

Scientists on our #JunoMission to Jupiter have transformed data collected during recent flybys of Io into animations that highlight two of the Jovian moon’s most dramatic features: a mountain and a glass-smooth lake of cooling lava. See more science:

Another way to explore Mars virtually

What exactly are asteroids? Why do we track and explore them?

After riding to Saturn aboard NASA's Cassini spacecraft, 20 years ago today European Space Agency's Huygens probe made the first landing on a world in the outer solar system when it descended through Titan's thick atmosphere.

A partial lunar eclipse darkens the full Moon on Aug. 27. About 96% of the Moon slips into Earth's shadow, turning most of it red as our atmosphere filters sunlight. Begins 10:34pm ET Aug. 27, peaks 12:12am ET Aug. 28. What to look for: 🌙 🎬: NASA's Scientific Visualization Studio/Ernie Wright

For a few million years, Earth may have been left out in the cold — literally. New NASA research shows the Sun's protective bubble has shrunk smaller than Earth's orbit at least three times in the past 10 million years, possibly triggering ancient ice ages. 🌍 Full story:

On Aug. 12, a total solar eclipse will cross Iceland and Spain. NASA will be there! The U.S. won’t see totality this time, so we’re bringing the science to you. Follow along this week! ☀️

On Aug. 12, a total solar eclipse will cross Greenland, Iceland, and Spain — and NASA science will be there! ☀️🌑🔭 We're flying high-altitude jets and launching scientific balloons to study the Sun and the eclipse's effects on us: 📸: NASA/Ernie Wright

POV: You're flying by the Moon. This visualization is designed to show you what exactly the Artemis II astronauts will see outside their window during their lunar flyby. Here, the seven-hour visualization is compressed into 28 seconds. ⬇ (1/4)

"...copy, Moon joy."

A new study finds some human-delivered microbes could survive in niches near the Moon’s South Pole. 🦠 While there’s no evidence they can grow or replicate there, learning more about them can help protect future Moon &amp; Mars science from contamination.

Join us live on July 16 at 2 p.m. ET to meet the team building NASA’s Dragonfly, learn how it will explore Titan’s rich prebiotic chemistry (the molecules and processes that can lead to life), and see how the mission is coming together. Set a reminder:

NASA’s WB-57 jet studies eclipses from about 50,000 feet (15,000 meters) — above most of the haze and turbulence that blur the view below, for a sharper look at the Sun’s corona. The WB-57 will observe the Aug. 12 total solar eclipse from above. More:

For a couple of minutes on Aug. 12, the Sun all but disappears in the middle of the day. NASA-funded student teams will launch research balloons from Iceland and Spain to track how the lowest layer of the atmosphere responds.🎈 More:

On Aug. 12, a total solar eclipse crosses Iceland and Spain. Iceland’s volcanic terrain helped train the Artemis II Moon crew; Spain offers clearer skies. NASA-funded teams are in both — because spreading out is how you beat the clouds. Watch live with NASA:

NASA’s ESCAPADE mission, our next science mission to Mars, has a new launch date: today! The launch window opens at 2:57 p.m. EST. Yesterday's launch attempt was postponed due to the intense geomagnetic storm that rocked our planet. Learn more:

Right now, the Artemis II astronauts are farther from Earth than anyone has ever been before. Live coverage:

One week in the solar system 🪐 Even as NASA Artemis II was making its historic trip to the Moon, several other NASA missions were exploring all across the solar system. Here are just a few of the images some of them captured during one week

Some things our Psyche spacecraft picked up during its brief visit to Mars in May: - 1000 MPH speed boost - 3-degree trajectory adjustment - Science data - Lots of pictures!

We've spotted the #OSIRISREx capsule on the ground, the parachute has separated, and the helicopters are arriving at the site. We're ready to recover that sample!

The Dragonfly mission is flying through milestones! Recent thermal and environmental testing shows how the rotorcraft will survive and navigate Titan’s skies. This bold mission will explore one of our solar system’s most intriguing worlds.

Smile! Tomorrow is the Northern Hemisphere’s summer solstice! 😎☀️ This “sunny smile” is made of coronal holes — darker, cooler regions on the Sun where solar material escapes to space at incredible speeds. 🕳️ More on coronal holes in this episode of NASA’s Illuminate.👇

What's Up for July? A predawn meetup between the Moon and planets, a returning comet, dark skies for the Milky Way, and Saturn's unusually thin rings.

A new study finds some human-delivered microbes could survive in niches near the Moon’s South Pole. 🦠 While there’s no evidence they can grow or replicate there, learning more about them can help protect future Moon & Mars science from contamination.
