Using NASA’s James Webb Space Telescope (JWST), an international team identified a supernova’s source star, or progenitor, for the first time. The observations - combined with archival images from the ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

An international team of astronomers has, for the first time, successfully probed the early universe. An international group of astronomers has reached a new milestone in studying the early universe.

One such superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational ...

The most detailed glimpse yet of a doomed star hidden in dust before it exploded has been captured by astronomers. Using NASA’s James Webb Space Telescope (JWST), an international team identified a ...
