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.

Columbia Professor Brian Metzger helped other astronomers interpret their observations of the unexpected stellar event.

The results indicate that the elements essential for life formed within extreme, highly energetic environments deep inside stars, far removed from the calm conditions required for life itself. The ...

A rare supernova let scientists glimpse a star's interior, revealing a dense silicon-sulphur shell and unexpected helium that should have vanished earlier. (Nanowerk News) An exploding star has given ...
