A star in a galaxy far, far away is consumed by a black hole.
What happens when a star gets too close to a black hole? Astronomers were lucky enough to find out as they watched this chance phenomenon, which happens about once every 100,000 years, unfold in a distant galaxy. First, the black hole's gravitational forces ripped the star apart, unleashing a stream of stellar fragments. Bits of ionized gas swirled around the black hole along elliptical paths, while other pieces of the star blasted into space. As the orbiting debris fell toward the black hole, colliding gas particles generated intense heat and light that could be seen from Earth. Astronomers looking through wide-field telescopes saw a bluish glow in the region of night sky where the galaxy is located. Instruments aboard NASA's Galaxy Evolution Explorer (GALEX) spacecraft also detected the increase in brightness, which lasted months. The computer simulation shows a star being shredded by the gravitational forces of a massive black hole.
