A supernova is a brilliant end to a giant star. For a brief moment of cosmic time, a star makes one last effort to keep shining, only to fade and collapse on itself. The end result is either a neutron star or a stellar-mass ...

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from ...

Astronomers from Germany and China have performed detailed radio observations of a supernova remnant (SNR) known as G107.0+9.0. Results of the observational campaign yield important insights into the radio properties of this ...
Astronomers have used ESA's XMM-Newton spacecraft to investigate the overionized recombining plasma in a supernova remnant (SNR) known as IC 443. Results of this research, published August 12 on arXiv.org, deliver essential ...
Astronomers have succeeded for the first time in quantifying the proton and electron components of cosmic rays in a supernova remnant. At least 70% of the very-high-energy gamma rays emitted from cosmic rays are due to relativistic ...
