NASA is credited for this discovery. Its Swift satellite detected last month a brightening X-ray source. Next Astronomers studied that area of our galaxy and positively identified a bright X-ray nova that formed because a stream of gas was directed either to a black hole or to a neutron star.
Unlike a supernova, which is the shock wave that sweeps up the expanding shell of dust and gas, a nova is the cataclysmic explosion of a white dwarf star. Furthermore, as opposed to a supernova, a nova does not completely destroy a star
Astronomers named the black hole X-ray nova Swift J1745-26. This previously hidden black hole is located somewhere around 30000 light years away from Earth, in the middle of our Milky Way galaxy. Witnessing such an event is extremely rare.
