Researchers were alerted to the possible black hole after telescopes watching for changes in the brightness of stars captured some anomalies about 5,000 light-years away in the Carina-Sagittarius spiral arm of our galaxy, NASA said.

What sends a black hole into motion? When a star explodes in a supernova, gravity crushes its core and creates a black hole. Two astronomical research teams have announced they used Hubble Space Telescope data to find, for the first time, what appears to be a black hole moving through our galaxy. Since black holes are invisible, they are identified by statistical means or by seeing a black hole’s effects on another star or a second black hole. But moving black holes – ghostly remains of collapsed stars – have been impossibly elusive.Īstronomers estimate there may be 100 million black holes roaming through our galaxy, based on the Milky Way's 100 billion stars (some of which eventually collapse and become black holes). But did you know there may be millions of them drifting like ghosts throughout our galaxy? Watch Video: Rogue wandering black hole? Neuton star? Scientist studying galactic anomaly
