Simulation: black hole catches star - 2011
Simulation - Black hole catches star
|Computer simulation created by NASA (20114) showing a star being shredded by the gravity of a massive black hole, with some of the stellar debris falling into the black hole and some of it being ejected into space at high speeds, according to the physical laws of conservation of energy (Croswell, 20111). The elapsed time corresponds to the amount of time it takes for a Sun-like star to be ripped apart by a black hole a million times more massive than the Sun (HubbleSite, 20113). The simulation is based on data from Gezari et al (20112).|
