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.

Neutron stars smashing together may create and trap ghost particles called neutrinos, and this discovery could help us better understand how elements like gold are forged.

The Gaia space telescope has spotted the dim companions of eight bright stars, suggesting we can expect new glimpses of distant planets.

A low-mass star races through the Milky Way at over a million miles per hour, a journey that began with either the supernova explosion of a vampire star or an encounter with black holes.

Astronomers using the CHIME telescope are looking at strange, one-off cosmic explosions with a new angle. This could bring us closer to solving the lingering mystery of fast radio bursts.

NASA's NuSTAR telescope found evidence of cosmic fireworks and X-ray echoes coming from the Milky Way's supermassive black hole Sagittarius A*.

NASA's Chandra X-ray space telescope has imaged Westerlund 1, the largest and closest super star cluster to Earth, in stunning detail.

Hubble has mapped the outflow "burps" of a nearby feeding supermassive black hole-powered quasar for the first time, measuring speeds of 6.5 million mph, around 8,500 times the speed of sound.

The JWST has proven itself to be a "supernova discovery machine" by finding 80 exploding stars in the infant universe, including the most distant and earliest supernova ever seen.

The sun protects our solar system's planets from the harsh environment of interstellar space; 2 million years ago, a dense cloud of matter could have curtailed this shielding.

The James Webb Space Telescope has seen signs of a violent asteroid collision in neighboring star system, Beta Pictoris. The observations could reveal the early stages of planet birth.

In a new video, NASA astronauts Butch Wilmore and Suni Williams conduct a guided tour of Starliner, the Boeing craft that carried them to the International Space Station last week.
