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

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

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

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

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

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 ...

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 ...

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 ...

A massive star in the Andromeda Galaxy, one of the most luminous objects in its neighborhood, has quietly disappeared. Over the span of roughly eight years, the star dimmed by more than 10,000 times ...
