Astronomers report the discovery of a new massive and quiescent galaxy at a high redshift. The galaxy, which received designation COSMOS-1047519, was detected using the Keck I telescope. The finding was detailed in a paper ...
Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models. These models estimate the universe to be 13.8 billion years in age, based on the big-bang expanding ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has performed deep spectroscopic observations of a galaxy known as COSMOS-1142. As a result, they detected massive and multiphase outflow of ...
Astronomers have made a thorough forensic study of a star that was torn apart when it ventured too close to a giant black hole and then had its insides tossed out into space.
