Closest known black hole to Earth spotted

CAPE CANAVERAL, Fla. — Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away.

Scientists reported, Friday, that this black hole is 10 times more massive than our sun. And it’s three times closer than the previous record-holder.

It was identified by observing the motion of its companion star, which orbits the black hole at about the same distance as Earth orbits the sun.

The black hole was initially identified using the European Space Agency’s Gaia spacecraft, said Kareem El-Badry of the Harvard-Smithsonian Center for Astrophysics.

El-Badry and his team are uncertain how the system formed in the Milky Way. Named Gaia BH1, it’s located in the constellation Ophiuchus, the serpent-bearer.
