Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

On Wednesday (Oct.2), an annular eclipse will sweep over the globe; here is what you can expect from this ring of fire eclipse, including how it will progress.

Scientists calculated that, on Sunday (Sept. 29), our planet should have captured the asteroid 2024 PT5, claiming it as a very temporary "mini-moon."

Could dark matter decay have given massive clouds of hydrogen gas the time they needed to birth supermassive black holes seen by the James Webb Space Telescope?

A 13-year survey conducted by the VISTA telescope has resulted in the creation of the most detailed Milky Way map ever. It contains a stunning 1.5 billion objects.

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.
