The Curiosity rover, which is designed to explore Mars, has found an ancient oasis on Mars. Researchers working with the Curiosity rover have found salt-enriched…
A supermassive black hole in the heart of Milky Way galaxy is going to absorb the large cloud of gas – the actual way that black holes are usually fed. Scientists confirm that the huge black hole, which has already named Sagittarius A* and is larger 4.3 million times than the Sun, will completely ingest the large gas cloud in 2012 or 2013. The black hole was detected by the produced intense radio emissions, the extraordinary amount of light and radio waves caused by its super-heated rushing towards the point of no return. Except the mentioned processes and some X-ray or infrared activity, the activity around Sagittarius A* is rather low which limits scientists in detecting processes happening in the black hole.
Since 2002, astronomers were monitoring a dusty gas cloud that is three times larger of the Earth mass and is moving in 5.2 million mph (8.4 million kph) in a straight line toward the Sagittarius A* black hole. The dusty gas cloud is growing as it moves towards the black hole’s accretion zone. With the special telescopes, scientists confirm that massive gas cloud has started to disrupt as it reached the black hole – changes in the dusty cloud constitution are visible in real time. The ingestion will become even more dramatic as the Sagittarius A* black hole will disrupt the most part of the gas cloud. Along with gas cloud falling into the black hole, its X-ray emission should become significantly brighter and should produce large amount of radiation in the next few years. Scientists hope that monitoring of the gas cloud ingestion by Milky Way galaxy’s Sagittarius A* black hole will answer numerous questions about how black holes are fed and functioning.
