#3c 58

Astronomers have discovered in their research that the interior of neutron stars may contain a type of ultra-dense matter that cannot be found elsewhere in the universe. In a press release issued on June 20, NASA stated that the center of the supernova remnant 3C 58 contains a rotating neutron star called PSR J0205+6449. Astronomers have studied this neutron star and other similar neutron stars…

The Milky Way Supernova You've Never Heard Of

A newly measured distance to stellar debris in the northern sky links it more firmly to an explosion observers saw in 1181

Every year astronomers see hundreds of supernovae erupt in other galaxies, but from such great distances these stellar explosions look only like bright dots. Researchers therefore prize the few supernovae that past observers witnessed in the Milky Way, where telescopes can scrutinize the wreckage. Since the year A.D. 1000, skywatchers have seen five of our galaxy's stars die in brilliant explosions. Now a new distance determination to the most mysterious of these is yielding new insight into its nature.
