A "guest star," briefly seen in 1181, was created by colliding dead stars.

China aims to launch its first planetary defense mission by 2030, to showcase the skills needed to nudge a dangerous asteroid away from Earth.

The Hubble Telescope has discovered a black hole "frozen in time" that's also the closest massive black hole to Earth.

In 1986, the Voyager 2 spacecraft discovered Uranus has a strangely weak radiation belt. Now, researchers think this could be linked to "traffic jams" caused by the world's warped magnetic field.

Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive supermassive black hole binary paintings than other galaxies.

As if deadly rains of glass, temperatures hot enough to melt lead, and sidewise 5,000 mph winds weren't unfriendly enough, the JWST has found a Jupiter-sized exoplanet also stinks of rotten eggs.

The expansion of the universe may not be accelerating at the edges of black holes. If this is the case at all event horizons, this may explain "Hubble tension," and the worst prediction in physics.

A Navy research team intern is part of a group of astronomers who have discovered a rapidly spinning neutron star, or "pulsar," in a dense cluster of stars around 10 light-years away.

Scientists will cool two pieces of quantum tech to a thousandth of a degree above absolute zero to hunt for two different dark matter suspects.

Just in time for Independence Day, the James Webb Space Telescope has imaged a red, white and blue fireworks display, courtesy of an infant star at the heart of a dense cloud of gas and dust.

The 'heartbeats' of rapidly spinning neutron stars are usually highly regular, but occasionally, the spin of these dead star pulsars 'glitches.' Now, a 'twisted' model could explain this mystery.

Astronomers have found two of the Milky Way's missing satellite galaxies, a step toward earning a better understanding of dark matter.

The James Webb Space Telescope found "tiny red dots" in the early universe representing overgrown supermassive black holes and stars that are impossibly old for the infant cosmos.

New research has identified two distinct populations of puffy, sub-Neptune exoplanets with low densities, allowing them to stay in step with their planetary siblings.

New research suggests some stars at the very heart of the Milky Way may have found an alternative fuel in the form of annihilating dark matter that grants them immortality.

After 20 years watching stars in the Large Magellanic Cloud for hints of a phenomenon predicted by Einstein, scientists throw doubt on the connection between ancient black holes and dark matter.

To celebrate its 25th anniversary, the Gemini North telescope team has released a stunning image of starburst galaxy NGC 4449, which is ablaze with intense star birth as it devours smaller galaxies.

The James Webb Space Telescope has discovered strange structures in the atmosphere of Jupiter over the solar system's largest storm, the Great Red Spot, proving the planet is full of surprises.

The JWST has detected star clusters that existed less than 500 million years after the Big Bang. These clusters, in the Cosmic Gems arc, could reveal secrets of cosmic evolution.

The James Webb Space Telescope saw a supermassive black hole that wasn't overfeeding when time began, deepening the mystery of how black hole grew so massive so quickly.

Using the ALMA radio telescope array, astronomers have investigated the disks of gas and dust around young binary stars to better understand how these systems procure planets.

Astronomers have measured supermassive black hole winds that existed when the universe was less than 3 billion years old, showing how these cosmic titans shape galaxies.
