Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...

A massive star in the Andromeda galaxy brightened in infrared light starting around 2014, then faded from optical view and ...

Core-collapse supernovae denote the violent deaths of massive stars, typically above eight solar masses, triggered when iron core fusion ceases and collapse ensues. The rebound of infalling layers, ...

Astronomers expanded this cosmic taxonomy in the 2010s by discovering superluminous supernovae. These rare explosions, ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

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 ...
