Mystery behind the origin of Black Holes appears to have solved by a team of scientists that came up with a new theory related to gas clouds. The theory revealed lately contradicts with two other ideas proposed earlier on the birth of supermassive black holes.

Black Holes is found in the heart of most of the galaxies including Milky Way, the planet earth is in. The origin of black hole, which is million times bigger than that one the Sun remains a mystery till date. One of the theories suggest that black holes originated by pulling gases from the surrounding areas while the other has it that many small black holes formed earlier merged together to form a massive one, according to Discovery News.

According to new theory proposed by astronomers using information from NASA's Chandra X-ray Observatory, Spitzer Space Telescope and Hubble Space Telescope, the black hole seeds were formed as a result of giant gas clouds collapsing with each other that missed out some intermediate steps. The findings are expected to be published in next edition of Monthly Notices of the Royal Astronomical Society.

"Our discovery, if confirmed, explains how these monster black holes were born," said Fabio Pacucci of Scuola Normale Superiore (SNS) in Pisa, Italy, who led the study, reported Space Ref. "We found evidence that supermassive black hole seeds can form directly from the collapse of a giant gas cloud, skipping any intermediate steps."

The astronomers believe that the black holes with billion times the mass of the sun are formed in less than billion years after the origin of the universe in the Big Bang. Andrea Grazian, a co-author from the National Institute for Astrophysics in Italy said that though it is difficult to unravel the origin of black hole seeds just yet, their research has brought two main candidates to limelight.

"There is a lot of controversy over which path these black holes take," said co-author Andrea Ferrara, also of SNS. "Our work suggests we are narrowing in on an answer, where the black holes start big and grow at the normal rate, rather than starting small and growing at a very fast rate."
