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.

The Red Planet has reached solar conjunction as its orbit takes it to the far side of the sun and out of sight. NASA's Mars robots are on their own until Nov. 25.

A tool bag that gave astronauts the slip during a spacewalk at the International Space Station is surprisingly bright and can be seen from Earth with binoculars.

Dubbed the "brightest of all time," or the BOAT, a gamma-ray burst detected in 2022 continues to astound astronomers, revealing severe effects in Earth's atmosphere.

Supermassive black hole Sagittarius A* is spinning nearly as fast as it can, dragging the very fabric of space-time with it and shaping the heart of the Milky Way.

More than 100 observed galaxies are being disrupted and stripped of their outer layers, transforming them into fossil-dense, ultra-compact dwarf galaxies.

A white dwarf spotted by the Gaia telescope was predicted to smash into our solar system in 29,000 years. But we'll be safe after all.

The newly identified quasar, observed 13.7 billion light-years away by the James Webb Space Telescope and Chandra X-ray Observatory, could be an example of a heavy black hole "seed" in the early universe.

The first images from ESA's dark universe detective Euclid are out, featuring spectacular views of nebulas, distant galaxies and globular clusters of thousands of stars.
