Cyg X-1: Can Black Holes Form in the Dark?

NASA APOD

COSMIC MESSAGE

Black holes are thought to form from the collapse of a massive star, usually heralded by a supernova explosion. This process is also a leading explanation for gamma-ray bursts. However, researchers suggest that Cygnus X-1, the Milky Way's most famous black hole, formed when a massive star collapsed without a supernova. Their dynamic evidence is summarized in this image of the region.
