Is a star about to explode in the night sky? If predictions come true, T Coronae Borealis (T CrB) could become visible for a ...

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

An international team analyzed data from NASA's Fermi space telescope and detected gamma rays from a rare and exceptionally ...

Brutal. The post Astronomers Say Star Self-Destructed So Catastrophically That It Left Behind No Trace of Its Existence ...

Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic ...

Through the years since it was first launched, the Hubble Space Telescope has captured stunning photographs of the Cassiopeia A.

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

Researchers leverage a multiangle simulations approach to elucidate the roles of neutrino fast flavor conversion affects core ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

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 ...

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...
