Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the ...

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 ...

A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in staggering numbers ...

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, ...

Learn about a bright blob in the central region of the Milky Way, illuminating what may be a remnant of a massive star that ...

“For nearly 20 years, astronomers have searched Fermi data for gamma-ray signals from thousands of supernovae, and while a ...

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 ...

NASA’s Fermi telescope may have finally uncovered the magnetic powerhouse behind the universe’s brightest supernovae.

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 ...

Astronomers working with two of the world’s most powerful X-ray telescopes have identified what appears to be a young ...
