Two brown dwarfs are whipping around each other in a tight tango — an unexpected dance for objects that are not-quite-stars and not-quite-planets.
A new analysis of samples from the asteroid Bennu has solved a long-standing mystery: Cracks in the boulders strewn across its surface masquerade as sand.
The Rubin Observatory has detected thousands of new asteroids, including several that spin a lot faster than expected for typical rubble piles.
The waxing Moon grows along the horns of Taurus, then passes first-quarter phase amid Jupiter and the heads of the Gemini twins.
When Andy Weir published Project Hail Mary, he based his novel on two worlds. We explore these planet candidates — and why they probably don’t exist.
Astronomers have used 40 years’ worth of data to peer inside the Sun, revealing that the solar cycle can leave a distinct fingerprint beneath the visible surface.
Artificial intelligence is revolutionizing our world — and how we interpret the heavens above us.
A rare, near perfect young-Moon challenge awaits North Americans after sunset on March 19th. Jupiter rules the evening from on high in central Gemini.

Samples returned from Ryugu contain all five nucleobases, just like from asteroid Bennu. The find suggests life’s ingredients could have come from outside Earth.
The Small Magellanic Cloud, a dwarf galaxy near the Milky Way, is undergoing a complete galactic transformation after a recent collision with its nearest neighbor.
Just 35 light-years away, in the southern constellation Volans, the Flying Fish, is a world unlike any other. The weird, low-density planet, known as L98-59 d, appears tohave a deep […]
The disk of gas that spirals onto a newborn magnetar wobbles, creating "bumps" in the brightness of the supernova that accompanied this object's birth.
Dozens on amateur astronomers helped measure the minuscule difference in Didymos’s trajectory around the Sun, after NASA’s DART mission impacted its moon.
While small galaxies are expected to have even smaller satellite galaxies, astronomers have found a surprising number of tiny companions around one dwarf galaxy.
The latest JWST images, along with archival images taken before the asteroid was even discovered, combine to refine its trajectory.
Bright Jupiter highlights the Gemini stick-figure twins standing on either side of it. Down below, the Winter Triangle balances on its Sirius point.
We live our lives in a blink of universal time.
The Vera Rubin Observatory is seeing 800,000 astronomical alerts per night — and that number will only increase.
