Two black holes on course to collide with force of 100million supernovae explosion THESE two black holes are on course to collide with each other sparking a cosmos-shaking explosion which will reverberate across the universe. The pair, called PG 1302-102, were first identified earlier this year using ground-based telescopes which picked up light signals being given off, and are the tightest orbiting pair of black holes ever detected. Entangled by gravity and destined to merge, the two, in a distant galaxy, appear to be locked in an intricate dance. Researchers using data from NASA's Galaxy Evolution Explorer (GALEX) and NASA's Hubble Space Telescope have come up with the most compelling confirmation yet for the existence of these merging black holes and have found new details about their odd, cyclical light signal. Researchers are now studying this pair to better understand how galaxies and the monstrous black holes at their cores merge - a common occurrence in the early universe. PG 1302-102 is one of only a handful of good binary black hole candidates. It was discovered earlier this year by researchers at the California Institute of Technology in Pasadena, after they scrutinised an unusual light signal coming from the centre of a galaxy. The researchers, who used telescopes in the Catalina Real-Time Transient Survey, demonstrated that the varying signal is likely generated by the motion of two black holes, which swing around each other every five years. While the black holes themselves don't give off light, the material surrounding them does. A new study, published in Nature, researchers found more evidence to support and confirm the close-knit dance of these black holes. Using ultraviolet data from GALEX and Hubble, they were able to track the system's changing light patterns over the past 20 years.
