Hubble spots a black hole casting shadows in space


NASA’s Hubble Space Telescope recently captured this sunset-esque view of the nearby galaxy IC 5063, located some 156 million light-years from Earth. Beams of light — along with their shadowy counterparts — seem to streak out from the center of this galaxy, just as sunlight creates similar shadows and beams of light during a cloudy sunset here on Earth. 

A team of researchers traced the rays and resulting shadows back to a supermassive black hole at the center of IC 5063. Because the blackhole is gobbling up nearby material at a rapid rate, its food piles up around it like too much water going down a small drain. This cosmic whirlpool causes the circling material to heat up and glow around the otherwise black hole. In their paper, published October 10 in The Astrophysical Journal Letters, the teams suggests that a donut-shaped ring (or torus) of dusty material is surrounding the black hole, continuously feeding it. 

The light then hits dense patches in the dust ring, which casts shadows out into space. And thanks to the orientation of the black hole compared to its galaxy, the beams of light and the shadows are visible to us here on Earth.
