Fact Sheet
Stellar Odd Couple
A black hole "steals" gas from the surface of a supergiant companion star in this artist's concept of the star system Cygnus X-1. The hot gas forms a disk around the black hole, and powerful magnetic fields funnel some of the material back into space in high-speed jets. [ESA/Hubble European Space Agency Information Centre (M.
