Image of Cygnus X-1, the Milky Way's most famous black hole, and the massive star cluster Cygnus OB3. Arrows indicate similar motion between Cyg X-1 and the stars in Cyg OB3, suggesting that Cyg X-1's progenitor star collapsed without a supernova explosion, potentially creating a dark gamma-ray burst.
