The US National Aeronautics and Space Administration (NASA) announced on Monday that it has discovered the youngest black hole known to exist in our cosmic neighborhood. The 30-year-old black hole, known as Supernova 1979C (SN 1979C), is about 51 million light years from Earth and occurred in galaxy M-100.
美国宇航局日前发现一个地球附近最为年轻的黑洞。据了解，该黑洞年仅30岁，系距离地球约5100万光年的M100星系中的超新星“SN1979C”的余烬。

NASA's Chandra X-ray Observatory has revealed a bright source of X-rays that has remained steady during observation from 1995 to 2007. This data suggests that the object is a black hole being fed either by material falling into it from the supernova or a binary companion.
根据美国宇航局钱德拉X射线望远镜获得的数据，一个明亮的X射线源在1995年到2007年这段观测期内保持稳定。科学家据此推断该射线源是一个黑洞，其正在吞噬超新星“SN1979C”及其伴星落下的物质。
