Astronomers have spotted a rare X-ray star explosion near the center of our Milky Way galaxy, revealing a previously unknown black hole munching on gas from a neighboring sun-like star.
NASA's Swift satellite made the cosmic find last month when it detected a new and rapidly brightening X-ray source a few degrees from the galactic center of the Milky Way.
Astronomers identified the outburst as a short-lived bright X-ray nova, which is produced when a stream of gas rushes toward either a neutron star or a black hole. Unlike a supernova, which is the explosive death of a star, novas are smaller explosions that do not completely destroy a star.
