Astronomers working for NASA have discovered two black holes that are on a collision course.

Now if you think about how powerful they say one black hole is, imagine the damage two black holes could do. Yeah, a lot. Which they say the damage could result in a whole galaxy being wiped out due to these merging black holes.

The distance between them has been estimated at about one million light years away or the diameter of our solar system

Researchers also predict that when they do the merge, which is estimated to be within a million years, the collision will have the power of 100 million supernovae (thats superpowerful).

Black hole mergers are considered to be the most violent events in the Universe.

When they finally meet, they converge in a type of death spiral, and are predicted to send out ripples known as gravitational waves, a theory devised by Albert Einstein 100 years ago.

Scientists at the California Institute of Pasadena who are trying to gauge a better understanding of how galaxies and black holes merge, first found the pair earlier this year after finding an unusual light signal coming from the centre of a galaxy, named PG 1302-102.
