Astronomers spotted nine galaxies with characteristics that have never been seen as a collection before. It's possible this is a newly found type of star-forming galaxy. When you purchase through ...

Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active ...

The James Webb Space Telescope has turned its infrared gaze on the early universe and found something that should not quite exist: compact objects that look like stars in a telescope image but behave ...

Hubble has revealed a strange cosmic object called Cloud-9, a dark matter–dominated cloud with no stars at all. Scientists believe it is a “failed galaxy,” a leftover building block from the early ...

Strange cosmic objects spotted by NASA's James Webb Space Telescope (JWST) are presently puzzling astronomers. The odd observations show features of both stars and galaxies, leading to researchers ...

Astronomers announced the discovery of a starless cloud of hydrogen gas, a pristine relic of the cosmos that is almost as old as time itself. By Katrina Miller The universe continues to surprise those ...

Current theories say young galaxy clusters should be relatively cool compared to older ones. But researchers recently found a very young cluster that was shockingly hot. Study author Dazhi Zhou says ...
