A newly discovered Earth-size world orbiting a dead white dwarf star gives scientists a hint of what the solar system may look like in billions of years.

New research suggests that the atmosphere of Mars could have literally "gone to ground" as carbon dioxide was greedily slurped out of the atmosphere and locked away by Red Planet clays.

Using the Dark Energy Camera, astronomers discovered that black-hole-powered quasars in the early universe lived in dense neighborhoods, but were "bad neighbors."

Using the James Webb Space Telescope astronomers have found that a strange inflated exoplanet is even weirder than they realized finding a strange asymmetry in its atmosphere.

Astronomers have discovered a "missing link:" a tiny black hole lurking with a red giant star in a strange and difficult-to-explain binary system.

The sunspot AR3835 erupted on Sunday (Sept. 22) during Earth's equinox when even a glancing blow can cause a geomagnetic storm.

The Hubble tension, a longstanding problem in cosmology, could potentially be relieved if early dark energy is taken into account.

The largest Einstein Cross dwells among a rare arrangement of seven gravitationally lensed galaxies called the Carousel Lens located between 7 billion and 12 billion light-years from Earth.

Astronomers have cataloged over 500 gamma-ray bursts, which are some of the most violent explosions in the cosmos.

The first results from JAXA's XRISM X-ray telescope are out, and they reveal new features of the superheated gas around a distant supermassive black hole and a closer supernova.

Astronomers have discovered a hidden feature in exoplanet distribution that could explain the absence of so-called "hot-Neptunes" close to their stars.

Tiny black hole "bullets" left over from the Big Bang could be passing through Mars at speeds in excess of 7,000 times the speed of sound, causing the Red Planet to "wobble."

The James Webb Space Telescope has imaged a collision between two galaxies that appears to have created a beaming smile in space.

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

Earth will grab itself another moon this month, but only briefly. The "mini-moon" in the form of asteroid 2024 PT5 will stick around for just two months.

A distant star has a dead star companion lurking in its vicinity that could be a monster-massive white dwarf, raising the question: how has it avoided being devoured by this cosmic zombie?

Using the James Webb Space Telescope astronomers have observed a supermassive black hole "killing" its galaxy by starving it of the material needed to birth new stars.

A chance encounter with another asteroid could steer Apophis destructively close to Earth during a future passage.

The James Webb Space Telescope has taken things to the extreme, studying the outer edge of our own galaxy, the Milky Way and producing a stunning new image.

"Iron Winds and Metal Rain." Not the title of a heavy metal album but an accurate weather prediction for a hellish exoplanet called WASP-76b.

The current generation of gravitational wave detectors could "hear" supernovas over 65 million light-years away, helping scientists determine if a dying star creates a black hole or a neutron star.

Was Ceres born in the main asteroid belt, or did it migrate there from the outer solar system? The answer is buried in data from NASA's Dawn spacecraft.

The tag team of NASA space telescopes Hubble and Chandra has demonstrated that two is definitely better than one when it comes to pairings of supermassive black holes and hunting for them.

Many red supergiant monster stars lurk in a Milky Way cluster astronomers have discovered with the Gaia space telescope. The cluster, Barbá 2, could help understand why some stars become black holes.

Scientists have "boldly gone" where no one has gone before, discovering what would happen if a faster-than-light warp drive like the one used in Star Trek were to fail.
