"The planet is basically super fluffy."

The discovery could help astronomers better understand how cosmic magnetic fields form and evolve.

Astronomers have discovered an Earth-size planet orbiting a red dwarf star, making just the second planetary system seen around one of these tiny, cool, dim, but common, stars.

NASA's Chandra X-ray space telescope has spotted the supermassive black hole at the heart of our galaxy erupting, proving even quiet black holes like Sagittarius A* need to vent sometimes.

Some black hole pairs roll around each other in wobbly, egg-shaped orbits that could hold clues about their origins, gravitational wave measurements suggest.

NASA's Nancy Grace Roman Telescope will hunt for the universe's first stars — or rather, what's left of them after they've been ripped apart by black holes.

Asteroid Apophis is heading to Earth, and scientists have revealed three tiny spacecraft concepts that could race to meet the space rock in April 2029.

The spacecraft XRISM has examined light from a distant galaxy that houses a supermassive black hole to determine the fate of matter in the void's gravitational thrall.

Primordial black holes left over from the Big Bang and no wider than a dime could be a prime target for NASA's Nancy Grace Roman Telescope after it launches in 2026.

Zombie white dwarf stars keep their heavy metal exteriors fresh by constantly cannibalizing any smaller objects in their dead planetary systems, like comets and asteroids, that get in their way.

NASA's exoplanet-hunting spacecraft TESS is back in action after nine days in safe mode, returning to scientific observations on May 3.

55 Cancri e is a super-Earth planet that appears composed of diamond-like carbon — now, thanks to the JWST, astronomers have found the world has "grown" a second atmosphere.

Black hole week is on, and to celebrate NASA is taking us on a way to plunge past the event horizon of a supermassive black hole and on a time-bending trip around the same cosmic titan.

The mystery of how early universe supermassive black holes grew so quickly may be solved, with the James Webb Space Telescope finding the first evidence of "heavy seeds."

There is nothing supernatural about this celestial structure, but it is awe-inspiring nonetheless.

Astronomers will be alerted to gravitational waves faster than ever before as LIGO and other detectors "listen" to a universal symphony.

New research may have identified a culprit molecule that caused Venus, often described as Earth's twin, to lose its water and become an inhospitable hellscape.

Thanks to XMM-Newton, astronomers may know the powerful event that gave rise to the Cloverleaf odd radio circle.

Scientists think they've uncovered a cosmic "glitch" in gravity that could require a revision in Einstein's theory of general relativity.

Reports of life signs detected in the atmosphere of the potential ocean world K2-18 b may have been premature.

Citizen scientists have spotted a truly remarkable planet in a binary system's habitable zone. They gave a Harry Potter-inspired nickname.

It may have fewer pixels than the screen of a 1989 Game Boy, but the Resolve device on the XRISM space telescope will broaden our view of the cosmos.

Both the Hubble Telescope and TESS exoplanet hunter went into safe mode on April 23. Hubble is back on, but TESS remains off.

WASP-12b is a planet on a date with a fiery destiny, doomed to plunge into its sun-like star. Scientists may finally know why some hot Jupiters eventually death spiral into their stars.

The JWST has performed a weather report for a distant hot Jupiter exoplanet, finding winds three times as fast as a jet fighter, clouds made of rock and temperatures hot enough to melt lead.
