Locked in an epic cosmic waltz 9 billion light years away, two
supermassive black holes appear to be orbiting around each
other every two years, according to NASA. The two giant bodies each have
masses that are hundreds of millions of times larger than that
of our sun, and the objects are separated by a distance
roughly 50 times that which separates our sun and Pluto.
When the pair merge in roughly 10,000 years, the titanic
collision is expected to shake space and time itself, sending
gravitational waves across the universe.
