有时粉色的黑洞更漂亮

This false-color image, taken by the Chandra X-Ray Observatory in 2012, shows an extraordinary outburst from a black hole – where its X-ray output increased at least 3,000 times – in the galaxy M83. Chandra observed what is called a ULX, or ultraluminous X-ray source. The remarkable behavior of this ULX in M83 provides direct evidence for a population of older, volatile, stellar-mass black holes.

这张由钱德拉X射线天文台于2012年拍摄的假彩色图像显示了M83星系中一个黑洞的异常爆发——其X射线输出至少增加了3000倍。钱德拉观测到了ULX，即超光X射线源。M83中的这个ULX的非凡行为，为更古老的、不稳定的、具有恒星质量的黑洞群提供了直接证据。
