Scientists Discover Closest Known Black Hole To Earth
Astronomers have discovered a new record-breaking black hole, which is the closest to Earth found to date — and one of the smallest.
Black holes can’t be seen because they emit no light, but they can be detected by their corresponding stars and eerie, powerful gravitational pull. Ohio State University researchers spotted this one by noting the distortion in the shape of a red giant star caused by the gravitational pull of its suspected companion black hole. It’s just 1,500 light years away from the Earth.
The possibility of a black hole in that space had been previously overlooked because this one is unusually small.
“Just as the moon’s gravity distorts the Earth’s oceans, causing the seas to bulge toward and away from the…
