The biggest hole formed from a collapsed star in the Milky Way Galaxy resides 2,000 light years away from Earth in the Aquila constellation. Researchers spotted the black hole when they noted the wiggle of a nearby orbiting star.
"No one was expecting to find a high-mass black hole lurking nearby, undetected so far," said Pasquale Panuzzo, an astronomer at the Observatoire de Paris, and one of the study authors, in a press release. "This is the kind of discovery you make once in your research life."
After noticing the wobble, the European Southern Observatory's Very Large Telescope and other Earth-bound observatories confirmed the size of the black hole. It's estimated it's about 33 times bigger than the Sun. Still, it is not the biggest black hole in the Milky Way galaxy; that title belongs to Sagittarius A, the supermassive black hole at the center of our Milky Way Galaxy.
