Scientists have successfully measured a monster black hole sitting at the center of a galaxy 73 million light years away from earth. And, the metrics they found are mind-boggling: the black hole is about 660 million times as massive as our sun, and a cloud of gas is speeding around it at about 1.8 million kmph.

These groundbreaking observations were made with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile by an international team of scientists that includes Rutgers associate professor Andrew J. Baker. ALMA, the world’s largest astronomical project, is a telescope with 66 radio antennas about 16,400 feet above sea level. It provides scientists with unprecedented accuracy in observations. The research is published in the Astrophysical Journal Letters.

Black holes – the most massive typically found at the centers of galaxies – are so dense that their gravity pulls in anything that’s close enough, including light, said Baker, an associate professor in the Astrophysics Group in Rutgers’ Department of Physics and Astronomy.

A black hole can form after matter, often from an exploding star, condenses via gravity. Supermassive black holes at the centers of massive galaxies grow by swallowing gas, stars and other black holes. But, said Baker, “just because there’s a black hole in your neighborhood, it does not act like a cosmic vacuum cleaner.”
