Supermassive Black Holes, 超大質量黑洞

The spiral galaxy NGC 4845, located over 65 million light-years away in the constellation of Virgo (The Virgin) is shown in this NASA/ESA Hubble Space Telescope image released on January 8, 2016. The galaxy's orientation clearly reveals the galaxy's striking spiral structure: a flat and dust-mottled disc surrounding a bright galactic bulge. NGC 4845's glowing center hosts a gigantic version of a black hole, known as a supermassive black hole. (Photo by Reuters/NASA)
