The Habitable Worlds Observatory is poised to tell us whether Earthlike planets are common—if it can get off the ground ...

Dark comets have been observed by many telescopes over the years, but this time, NASA is uncertain about their origin. Unlike regular comets, these objects resemble an asteroid, but move like comets.

NASA's GRACE satellite detected a large gravity anomaly over the Atlantic Ocean. Meanwhile, Earth-based observatories saw a rapid shift in the planet's geomagnetic field.

In May 1964, Arno Penzias and Robert Wilson were testing how radio waves bounced off balloon satellites developed by Bell Telephone Laboratories. But they kept getting an unpleasant hissing noise, in ...

Lava planets, which have one face perpetually turned toward their star and heated to temperatures capable of melting rock, offer a unique natural laboratory for exploring the interactions ...

Just two decades after astronomers discovered the first exoplanet, NASA has confirmed the existence of 6,000 alien worlds. The total will rise even quicker as next-generation telescopes take flight.

Space is full of weird objects that don’t make sense according to what scientists thought they knew about the universe, […] ...

NASA’s exoplanet tally has climbed to 6,000, revealing bizarre and beautiful worlds far stranger than our own.

What can exoplanets orbiting M-dwarf stars teach scientists about planetary formation and evolution? This is what a recent study posted to the arXiv preprint server and submitted to the American ...

Fresh observations from the James Webb Space Telescope ( JWST) — the most detailed yet of the planet's upper atmosphere — reveal "dark beads" scattered through Saturn's glowing auroras and a ...

Something strange is stirring in Saturn’s skies. Astronomers using the James Webb Space Telescope have spotted something entirely new in Saturn’s atmosphere: a string of dark, bead-like features high ...
