Gaia BH1______3______(weigh) about 10 times the mass of the Sun and is about 1600 light-years (the distance light travels in one Earth year, about 6 trillion miles) from Earth in the Ophiuchus constellation (a group of stars in a pattern). A black hole is an area in space______4______its gravity is so strong that even light cannot escape______5______. Most known black holes are active, which means they are absorbing gas from nearby stars. This forms a ring around the black hole that scientists can see in x-rays. ______6______, Gaia BH1 is a dormant (休眠的) black hole, meaning it is not absorbing material from stars. To find Gaia BH1, a team of astronomers led by Kareem El-Badry looked at a map of stars taken by the European Space Agency`s Gaia spacecraft.
