Researchers Unveil More Facts About Andromeda Galaxy and its Exotic X-ray Signal
Information released by NASAâ€™s Chandra X-ray observatory in the year 2009 first informed the world about noticing an ULX (ultra luminous X-ray source) in the Andromeda galaxy following which, the astronomers started their studies to collect more details about the source and its galaxy, which is according to scientific calculations, 2.5 million light-years away from our Milky Way galaxy.
Findings of studies led by a team of astronomers have recently revealed about an extremely bright and shining X-ray beacon in the Andromeda galaxy, which they doubt is actually a black hole, gulping up matter i. e. the surrounding gases and dust around at a furious pace resulting in forming a massive disk that continues heating up and unleashing X-ray jets.
The above findings have been proved by an international team of scientists from their studies, who said that a stellar black hole is the cause behind this extremely bright object that is rapidly guzzling all its surrounding matter.
Researchers have declared this ULX to be the closest one that has been seen till date to our galaxy.
According to scientific research, formation of a Stellar black hole is the result of collapse of massive stars, which gives the hole a massive size i. e. approx 10 or 20 times bigger than the mass of sun.
Researcherâ€™s study says that the black hole behind the ULX object in Andromeda is not less than 13 times massive than sun, which would have been formed due to the end of a massive star that ended its life in a spectacular supernova explosion.
"ULX sources are still pretty exotic," study leader Matt Middleton, a research associate in the Department of Physics at Durham University in the U. K., said in a statement.
