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.

Using NASA’s Chandra X-ray space telescope, scientists have investigated if nearby exoplanets could support life, or if their stars are blasting them with too much deadly high-energy radiation.

By precisely tracking the orbit of over 156,000 asteroids, the ESA star-surveying satellite Gaia has potentially found over 350 previously undiscovered asteroid-moon binaries.

By examining a distant supermassive black hole, astronomers using the James Webb Space Telescope have found a shocking link between jets and dust around these cosmic titans.

Scientists have tracked mysterious, violent blasts of radiation called fast radio bursts to plasma-blowing, highly magnetic dead stars or magnetars.

V889 Herculis is an oddball unlike any other star we've ever seen. The nearby sun-like star rotates in a strange way that defies prediction.

Planets orbiting red dwarf stars may have a harder time hanging on to the conditions needed for life to arise and survive than previously thought, data from NASA's dead space telescope GALEX reveals.

Ten neutron stars found lurking in the Milky Way include cosmic black widows killing stars with "webs" of viscous plasma and a speed demon that spins over 700 times per second.

The sun could collect rogue planets and hold them at the outskirts of the solar system for millions of years, occasionally trading them with neighboring star Alpha Centauri.

New research using Apollo mission samples has determined that the impact of meteorites on the lunar surface is primarily responsible for generating the moon's thin and nebulous atmosphere.

Particle accelerators like the Large Hadron Collider have failed to turn up potential dark matter candidates, but could galaxy cluster smashes be used as cosmic dark matter colliders?

NASA's Roman Space Telescope will look all the way back to cosmic dawn 400 million years after the Big Bang to discover how the universe fundamentally changed at this crucial point in its history.

Astronomers have discovered that Saturn has thrown a newly found comet on its way out of the solar system. Comet A117uUD is expected to go interstellar at 6,700 mph.

Using data from the Hubble and Chandra space telescopes, scientists have determined that dark matter ghosted through the wreckage of two colliding galaxy clusters over 5 billion light-years away.

Scientists have analyzed images of the twin asteroids Didymos and Dimorphous taken by NASA's DART mission before it impacted the smaller space rock, revealing their age and origins.
