The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks ...
After a hot, compact neutron star forms from the collapsed iron core of a massive star, axions should be produced in immense quantities for about 10 seconds. Some of these axions (a, red dotted line) ...
A long observation with NASA’s Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space. The deduced ...
