Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that exploded millions of years ago. The star, which was in a nearby galaxy, exploded ...

When Japan’s Hitomi satellite trained its X-ray spectrometer on the Perseus Cluster in early 2016, it had just weeks to live.

An Australian-led study published in Nature found evidence of rare exploding stars called pair-instability supernovae, revealing a “forbidden gap” in black hole masses and offering new insights into h ...

Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

The study, published in Nature, uses gravitational wave observations to probe how the most massive stars end their lives, strengthening the case for a long-predicted "forbidden gap" in black-hole ...
