According to NASA, astronomers, using Chandra X-ray observatory had almost found a youngest possible Black hole known to exist in our cosmic background, and they even said that it appears to be our nearest possible. The 30-year-old object provides a unique opportunity for them to watch a black hole develop from infancy.The black hole appears to be the remnant of SN 1979C, a supernova in the galaxy M100 approximately 50 million light years away from the earth. NASA's Swift satellite, the European Space Agency's XMM-Newton and the German ROSAT observatory revealed a steady flow of bright X rays from a source during their observation from 1995 to 2007. and suggests that this could be the black hole being fed through the material that is falling in to it from the supernova or possibly from a binary companion."If our interpretation is correct, this is the nearest example where the birth of a black hole has been observed," said Daniel Patnaude of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. who led the study.Scientists think that the SN 1979C--first discovered by an amateur astronomer in 1979--was formed when a star about 20 times more massive than the sun collapsed--gravitational collapse.SN1979C, obviously is ...
