Using the James Webb Space Telescope, astronomers have investigated the giant exoplanet 29 Cygni b — work that could clarify the line between planets and stars.
The Dark Energy Spectroscopic Instrument has completed its five-year mission to build the most comprehensive 3D map of the universe to date — but its exploration of the universe continues.
The Jupiter-bound spacecraft JUICE spotted the interstellar invader comet 3I/ATLAS spraying enough water into space to fill 70 swimming pools a day.
"The discovery of this exceptional object has allowed us to accurately study the nature of the stars at the center of an elliptical galaxy in a remote era of the universe, when the galaxy was still young."
Gravitational waves may have provided the first tantalizing evidence of tiny primordial black holes born during the Big Bang, which could account for dark matter.
"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles are produced."
"It is fascinating that an active galactic nucleus can change its brightness so dramatically over such a short period of time."
Astronomers have discovered that rapidly spinning extreme dead stars or pulsars push it to the edge, blasting out radio signals from their extremities.
Using the James Webb Space Telescope, astronomers have investigated the star-forming region W51, resulting in stunning new images.
NASA's Artemis 2 has launched on a history-making journey around the moon and back, and the moment was captured from space.
The launch of NASA's historic Artemis 2 mission looks incredible in these stunning launch photos.
A Virtual Telescope Project livestream aims to track NASA's Artemis 2 Orion spacecraft — here's how to watch it as it travels through space.
SpaceX Starlink spacecraft was seen prior to breaking up in orbit by a satellite.
"A better understanding of Saturn’s environment is especially urgent now as plans for our return to Saturn and its moon Enceladus start to be developed."
NASA's XRISM X-ray spacecraft has clocked 2 million mph winds ripping out of a distant galaxy bursting with star formation.
Astronomers have spotted the most distant and brightest "space laser" ever seen, and it's blasting from a galaxy collision that occurred when the universe was half its current age.
Astronomers have discovered an additional 100 new worlds in data collected by NASA's exoplanet-hunting spacecraft TESS, thanks to an innovative AI program.
Astronomers have used the XRISM X-ray spacecraft to discover a star being devoured by a stellar companion, solving a mystery that has baffled scientists for over 100 years.
Astronomers have spotted two planets forming around a distant infant star, offering a time capsule into see what the solar system looked like billions of years ago.
"Failed star" brown dwarfs may get a second chance to shine by colliding and merging to birth a new star.
Did primordial black holes born during the Big Bang swallow the universe's antimatter, allowing matter to dominate the cosmos?
A cosmic explosion with an energy equivalent to the output of a billion suns went unnoticed by astronomers until they caught the "echo" of this gamma-ray burst.
"Cosmic archaeologists" have discovered an iron-deficient second-generation star, which provides evidence of how ancient stars enriched their successors.
