A new study suggests that an early version of Mars’s smaller moon Deimos was pulverized by its own debris, explaining the moon's oddities.

The waxing Moon marches east across the evening sky. It says hello to binary Gamma Arietis on Saturday, then occults some of the Pleiades for Europe on Tuesday. But it's past them by nightfall in North America.

New videos from the Solar Orbiter and the Chandra X-ray Observatory capture magnetic avalanches on the Sun and the exploding remnants of a star 17,000 light-years away.

Mira the Wonderful is back! Of course, it's always been there, but now it's near maximum brightness and easily visible with the unaided eye.

Congress has rejected a draconian budget request, passing a bill that funds the space agency similarly to 2025.

Astronomers have found two gravitationally lensed supernovae that are missing images. Those images' arrival will offer a measure of the universe's expansion.

This winter the biggest planet is the brightest. The brightest star pins the Winter Triangle. And did you know Capella and Rigel march in step?

Schmidt Sciences has unveiled details on four ambitious observatories to monitor the dynamic cosmos, with data from all four expected by 2029.

This year offers an interesting mix of celestial coverups: a total solar eclipse viewable from Spain and two deep lunar
eclipses (one total, one not quite) visible across North America. The fourth, an annular solar eclipse, will be confined to the bottom of the world.

Two new smallsat missions, named SPARCS and BlackCAT, promise to examine stellar flares and explosions in the early universe.

In new observations, astronomers detect a moving wake of gas in the outer layers of the red supergiant Betelgeuse, offering fresh evidence for a long-suspected secondary star.

The young, nearby star may be experiencing an episode of repeated, violent collisions within its forming planetary system.

NASA's new, small observatory — launched successfully on January 11th — has a big mission: to characterize exoplanet atmospheres.

These moonless evening offer the winter Milky Way arching high over the world. And, when will Betelgeuse stand straight over Sirius for you?

Astronomers discovered a cloud of hydrogen gas that’s devoid of stars. Held together by an invisible halo of dark matter, the starless cloud may elucidate its nature.

Observers across America may witness a special transit and shadow event of Jupiter’s moon on opposition day.

Jupiter's having a special moment! Don't miss the giant planet at its best when it reaches opposition this week.

Astronomers have measured the mass of a free-floating planet for the first time. Comparable to Saturn, it’s surprisingly massive for such rogue worlds.

For 2026, I want to be more myself — less stress and rumination, more centeredness and joy — and that’s going to necessitate a lot more time beneath the stars.

Many less massive galaxies appear to lack something astronomers thought was ubiquitous: a central, supermassive black hole.

The bright Moon shines over Jupiter, Pollux and Castor on Friday evening the 2nd, then
groups right up amidst them on Saturday the 3rd.
