OREANDA-NEWS NASA's Chandra Observatory has discovered a black hole that rotates slower than most of its fellows
This was stated on the official website of the observatory, reports Gazeta.ru.
The black hole is located inside the quasar H1821 + 643, which is located at a distance of 3.4 billion light-years away.
The object contains between three and thirty billion solar masses, making it one of the most massive black holes known.
In Chandra data, NASA astronomers found that the black hole rotates at a speed of half the speed of light, which is twice as slow as most black holes.
This rotation rate supports the theory that the most massive black holes grow by merging with other ones.
Such supermassive black holes undergo large rotational changes, including slowing down or rotating in the opposite direction.
In addition to X-ray images from the observatory, radio data, and optical images from the PanSTARRS telescope in Hawaii,scientists were able to calculate the black hole's rotational speed.
The data were collected over the course of one week.
