- Astronomers have detected a pair of supermassive black holes 750 million
light-years away from Earth in a separate giant galaxy.
- Courtesy of the National Science Foundation’s Very Long Baseline Array’s (VLBA) radio vision data on the orbital motion of the black holes has been captured.
- Together, the two black holes have a combined mass that is 15 billion times the mass of the Sun, which is 1.989 x 10^30 kilograms
or 330,000 times the mass of Earth.
- But most galaxies have supermassive
black holes that are millions or billions times larger than the Sun at
- What makes these two black holes unique is their distance
from one another: They’re relatively close to each other with only 24
light-years of distance between them. Read more (6/28/17)
