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.

If the gravitational wave background detected last year came from a "supercool" phase transition around the time of the Big Bang, they hint at new physics.

Supermassive black holes that shred and devour stars throw them up like a "bad curry" and cover themselves in the wreckage, sick new simulations reveal.

JUICE flew by Earth on Tuesday (Aug. 20), just a day after it zoomed past the moon. The spacecraft took also snapped some images of home before heading off to Venus.

Using the NASA exoplanet-hunting spacecraft TESS, astronomers have discovered a hot Jupiter dancing with a hidden super-Earth companion.

The "deaths" of galaxies are caused by their central supermassive black holes, and the "smoking gun" evidence of this connection takes an unexpected form.

Jupiter, Saturn, Neptune, and Uranus may dominate the solar system, but their formation remains mysterious. A new model could account for these planets' rapid and efficient births.

Neutron stars are the universe's most extreme stars, composed of matter so dense a teaspoon of it would weigh as much as Mt. Everest. So, when they collide, it's quite the event.

Though magnetars and pulsars are two distinct types of neutron stars, astronomers have spotted a magnetar mimicking a pulsar after launching a mysterious blast of intense radiation.

A newly discovered star 30 times as large as the sun has a baffling chemical composition that could provoke a revision to stellar evolution models.

Astronomers are investigating a cosmic crime scene to determine why the death of a massive star left behind a highly magnetic "corpse."

Astronomers have discovered a supermassive black hole violently shredding and devouring a star nine times as massive as the sun.

Small pairs of binary black holes could be used to play hide-and-seek' with elusive supermassive black hole binaries via gravitational waves carry the "baritone singing" of these cosmic titans.
