Using NASA's Chandra spacecraft, astronomers have found "danger zones" for worlds where planet-birthing disks are blasted with high-energy radiation from massive young stars and rapidly disintegrate.

The neutron star 4U 1820-30 is one of the fastest spinning bodies in the universe, spinning at 716 times a second and erupting like an atomic bomb, NASA's NICER telescope has found.

Black hole formation could be a little Big Bang in reverse, coupling the matter of a dying star with dark energy, the mysterious force driving the accelerating expansion of the universe.

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision that created the smallest black hole ever seen.

Halloween is here, and there is no better way to celebrate than with a blood-curdling image of the Dark Wolf Nebula looking like a cosmic werewolf poised to grab an unwitting victim.

The extreme qualities of neutron stars could mean these dead stellar remnants gather dense clouds of hypothetical particles called "axions" around them, potentially shedding light on dark matter.

Dark matter makes up 85% of the stuff in the cosmos, but scientists have no idea what it is. Can you solve the case?

In time for Halloween, we present seven terrifying cosmic monsters — and to meet your thirst for scares, we've added must-watch horror movies to this witches brew.

The James Webb Space Telescope has discovered brown dwarfs at the heart of planet-forming disks in the Orion nebula. The discovery could help reveal if these "failed stars" can have planets.

A 6-mile-thick shell of methane ice on Saturn's moon Titan could assist in the hunt for life signs arising from this moon's vast subsurface ocean.

The NASA mission to Europa has some stops to make on the way.

Using the James Webb Space Telescope, astronomers have potentially discovered the first brown dwarfs beyond the borders of the Milky Way galaxy.

The destructive power of asteroids is undeniable — just ask the dinosaurs. New research suggests a huge space rock that struck Earth over 3 billion years ago may have benefitted early life.

A zombie star has defied expectations by surviving a supernova explosion that should have destroyed it. The undead white star's "grave" is marked by a cosmic dandelion.

Saturn has finally joined the solar system's other giant planets in possessing a Trojan asteroid, but it may have stolen it. The bouncing asteroid seems to have originated in the Kuiper belt.

The first "black hole triple" system, consisting of a black hole hungrily feeding on a companion star orbited by a more distant star, hints at a gentle formation process without supernova explosions.

The James Webb Space Telescope has discovered lonely quasars in the early universe, with "empty larders" that defy theories surrounding their growth to monster sizes.

A map of gravity wells or "basins of attraction" in the local universe may resemble a Taylor Swift outfit, but they define the largest structure in the universe, the last line of your cosmic address.

Space.com talks to artist and author Martin Vargic, who is turning exoplanets into stunning and intricate art.

"Killer electrons" stashed in radiation belts around Earth could be dislodged by lightning to create a game of "cosmic pinball" that influences space weather around our planet.

The Hunter's Moon rose on Thursday (Oct. 17), becoming the biggest and brightest full moon of the year and wowing skywatchers around the globe with a spooky pre-Halloween show.

'Photosynthetic habitable zones' could exist beneath radiation-filtering ice on Mars, offering scientists another region in which to hunt for alien life.

The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

U.S. company Vast has unveiled Haven-2, its proposed commercial successor to the soon-to-be-retired International Space Station.
