A new study of Saturn's 'Death Star' moon Mimas finds evidence of a young, underground ocean that may be hospitable to early forms of life.

The James Webb Space Telescope has detected two alien planets orbiting white dwarfs, the collapsed husks of once-mighty stars. The discovery offers a hint of what our solar system will look like after the sun's eventual demise.

Astronomers investigated an active supermassive black hole at the heart of Perseus A using the Event Horizon Telescope, spotting an epic battle between gravity and magnetism.

New simulations show how thousands of galaxies evolve by traveling through the strands of gas, dust and stars that make up the universe's "cosmic web."

Team "pro-exomoon" is back to defend the discovery of the first and only exomoons potentially seen by humanity.

Organic matter found in samples of asteroid Ryugu suggests that ancient comets may be responsible for bringing the 'seeds of life' to Earth.

The powerful James Webb Space Telescope captured a starburst complex in the Large Magellanic Cloud, with stunning results.

The most sensitive image of a globular cluster, a tightly packed ball of ancient stars, has revealed a strange radio signal that could be a black hole.

A new cosmic crime scene reconstruction tells the full story of a star ripped apart by a ravenous black hole, revealing a previously unknown aspect of these tidal disruption events.

The most powerful and distant fast radio burst ever seen has been tracked to a "blob" of galaxies that existed when the universe was less than half its current age.

The Einstein Probe has left Earth to survey the cosmos for X-ray signals from feeding black holes, colliding neutron stars and exploding stars.

Later this year, NASA's Parker Solar Probe will come even closer to the sun than it has before, while traveling at record-breaking speeds.

The surface of Venus is a hellscape with temperatures hot enough to melt lead, but some regions of its atmosphere high over the surface remain cool enough to harbor ice and birth ghostly clouds.

"Continuous unmitigated subsidence on the U.S. East Coast should cause concern."

A new treatment of images collected by Voyager 2 in the late 1980s using data from the Hubble Space Telescope has revealed the actual colors of the solar system's distant ice giants, Neptune and Uranus.

New observations of the Small Magellanic Cloud show that it might actually be two galaxies disguised as one.

NASA's Chandra X-ray Observatory helped to build a particularly festive image of the gas, dust, and young stars of NGC 2264, also known as the "Christmas Tree Cluster."

New research suggests that if tiny primordial black holes created during the Big Bang exist, some of them may have been snared by stars and are now forced to eat their way out.

The fascinating patterns of 35 repeating fast radio bursts (FRBs) reveal new properties of these mysterious blasts of deep-space radiation that appear and disappear in milliseconds.

The discovery of stars with their outer layers of hydrogen stripped by companions fills a glaring hole in our understanding of supernovas and binary systems with colliding neutron stars.

The island forged in fire off the coast of Japan in Oct this year is still growing, as seen in a Copernicus Sentinel-2 image caught on Nov. 27.

Peering deep into 'The Brick,' a dark, chaotic gas cloud at the heart of the Milky Way, the James Webb Space Telescope uncovered secrets that could shake up theories of star formation.

The James Webb Space Telescope's discovery of water and other molecules in the inner region of a hot protoplanetary disk suggests that rocky, Earth-like planets may be able to form in some very extreme environments.

Six exoplanets with sizes between Earth and Neptune have been in rhythm with each other since they were born around the same star 4 billion years ago, new research suggests.

Regular high-energy pulses of gamma-ray radiation emerging from around the Milky Way's central black hole may be coming from a blob of matter whipping around at 30% the speed of light.
