Betelgeuse, one of the most famous stars, is set to go supernova soon. This event will make it shine as brightly as the full ...

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

NASA's Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of a highly magnetic dead star, or magnetar.

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

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

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 ...

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

Our universe, filled with galaxies and stars, is full of mysteries. Over the centuries, astronomers have observed and documented supernova—the ...

This collapse leads to a supernova explosion, leaving behind either a black hole or a neutron star.

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

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football ...
