Black hole,artwork. Surrounding gas and dust are spiralling into the black hole,dragged by immense gravitational forces. This forms an accretion disc (purple/yellow). The extreme conditions cause the emission of high-energy jets. A black hole is formed when the core of a star collapses under its own weight,increasing its gravitational field to the point where,beyond a boundary known as the event horizon,nothing,not even light,can escape. This leads to its black appearance. Only stars of a sufficient mass will form a black hole. In the background is the bright band of the stars of the Milky Way galaxy | |
