A solar eclipse, the Perseids, bright Venus after sunset, and a deep partial lunar eclipse highlight August’s skywatching. Skywatching Highlights Transcript A solar eclipse, one of the year’s best meteor showers, Venus at its brightest in the evening sky, and a lunar eclipse to close out the month. That’s “What’s Up” for August. On Aug. […]

On Wednesday, Aug. 12, a total solar eclipse will be visible in parts of Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain, and a small corner of Portugal. NASA will stream the eclipse live with views across the path and interviews with subject matter experts through a variety of platforms. Learn where to watch online: […]
NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth-based auroras. Results published Thursday in Nature Communications show the same mechanism that circulates and catapults charged particles into Earth’s atmosphere is happening at […]

A predawn Moon-and-planets meetup, a returning comet, a great chance to see the Milky Way, and Saturn’s rings at a new angle. Skywatching Highlights Transcript An early morning hangout with the Moon and planets, a comet swings by, prime time for the Milky Way, and Saturn’s rings shine at a new angle. That’s What’s Up […]

As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly warmed from its closest pass by the Sun, and its ancient ice had been converted […]

Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the […]

Venus and Jupiter meet after sunset, the Moon passes in front of Venus, summer begins, and deep-sky treasures rise into view.

In December 2023, scientists looking at Mars data stumbled across something completely unexpected — observations of an atmospheric effect never before seen in the Red Planet’s atmosphere. Using instruments aboard NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) mission, scientists identified a phenomenon known to occur in Earth’s magnetosphere, where charged particles are squeezed like toothpaste […]

Shooting stars before dawn, a brilliant meetup between the Moon and Venus and a rare blue moon to end the month.

After years of lab work, the results are in: A rock that NASA’s Curiosity Mars rover drilled and analyzed in 2020 includes the most diverse collection of organic molecules ever found on the Red Planet. Of the 21 carbon-containing molecules identified in the sample, seven of them were detected for the first time on Mars. […]
