Two Monster Black Holes Are Set To Collide With a Blast 100 Million Times Larger Than a Supernovae

A duo of supermassive black holes orbiting each other at the center of a distant galaxy are heading towards a huge collision that will generate one of the biggest explosions in the cosmos. The black holes are circling each other in a space not much bigger than our solar system at approximately seven per cent of the speed of light. 

Astronomers observing the pair of black holes said they are projected to crash into each other in less than a million years, generating a blast 100 million times more powerful than a supernovae. This system of binary black holes is known as PG 1302-102 and they were first discovered in January this year when astronomers detected an uncommon bright spot of UV light coming from the center of a galaxy.

Researchers have now used ultraviolet light data from Hubble Space Telescope and NASA's Galaxy Evolution Explorerer (Galex) to track down the light configurations over the past 20 years. They found the black holes are emitting a bizarre cyclic light pattern as one of them is engrossing more matter than the other black holes, heating up the neighboring matter to release energy. The researchers discovered that this black hole orbits the other black hole once every five years. They said they belive that by carefully observing the final moments of these black holes will help them search for gravitational waves. The two black holes will circle each other closer and closer to each other in a 'death spiral' just like ice skaters, creating warping space and time.

This phenomenon would help to verify theories about gravity first suggested by Albert Einstein nearly 100 years ago. Professor Zolt├ín Haiman, an astronomer at Columbia University in New York who directed the mission, said: “We are strengthening our ideas of what's going on in this system and starting to understand it better.”

The entangled dance of the two giant black holes is also discharging an odd light signal that seems to brighten every five years. This is only because of the 'blue shifting' effect, in which light is clutched to smaller wavelengths as it journeys toward us in the same way that a police car's siren squeals at greater frequencies as it mpvestoward you.

One other reason has to do with the colossal speed of the black hole. The brighter black hole is roving at nearly seven percent the speed of light – nearly47 million miles per hour.

At these speeds, which are called as relativistic, the light becomes enhanced and brighter. The study was published in journal Nature.
