![]() ![]() Astronomers find the fastest spinning black hole to date 8 ways you can see Einstein's theory of relativity in real life The researchers suspected that the mysterious wobble came from the invisible tugs of a black hole. By poring through Gaia’s data, the astronomers found one star that appeared to have a distinct wobble - a slight limp in the usually smooth path of its trajectory. To zero-in on the nearby black hole, the researchers turned to the European Space Agency’s Gaia spacecraft that has been mapping the positions and movements of the Milky Way’s roughly 2 billion stars. This halo comes from matter that is slowly being stripped and shredded from nearby stars, planets and nebulae.īut not all black holes are feeding, and finding these dormant monsters among the roughly 100 million stellar-mass black holes estimated to be lurking in the Milky Way requires an elaborate strategy. ![]() Beyond a boundary called the event horizon, nothing - not even light - can escape the new black hole’s gravitational pull.įeeding black holes are visible as a dark heart surrounded by a ring of fuzzy, warped light. It explodes outwards before collapsing in on itself, packing first its core, and later all the matter close to it, into a point of infinitesimal dimensions and infinite density - a singularity. Iron requires more energy to fuse than it releases, and the star can no longer withstand the immense gravitational forces generated by its enormous mass. But once this fusion process begins forming iron, the star is locked on a path to violent self-destruction. As larger stars approach the ends of their lives, they fuse heavier and heavier elements, such as silicon or magnesium, inside their burning cores. Black holes start out as large stars with a mass roughly five to 10 times that of the sun.
