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

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 ...

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

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.

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-collapse supernova explosions. (Nanowerk News) Core-collapse supernovae ...

Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

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 ...
