Astronomers Identify ‘Missing Link’ Mid-Sized Black Hole

宇航员发现中等规模黑洞

Scientists have identified a mid-sized black hole that could be the "missing link" to help us better understand these mysterious space objects.

Researchers used data from NASA's Hubble Space Telescope and two X-ray observatories to find the black hole, which was in the process of destroying a nearby star.

Black holes are extremely dense objects possessing gravitational pulls so powerful that not even light can escape.

The newly identified black hole is more than 50,000 times the mass of our sun. It sits about 740 million light years from Earth in a galaxy containing far fewer stars than our Milky Way. A light year is the distance light travels in a year, about 9.5 trillion kilometers.
