WEBVTT FILE 1 00:00:00.000 --> 00:00:04.000 [Dramatic music throughout] The Sun is the only object on screen and shrinks as the camera backs away from it. 2 00:00:04.000 --> 00:00:08.000 The 100,000-solar-mass black hole in dwarf galaxy J1601 casts a shadow smaller than the size of our Sun. 3 00:00:08.000 --> 00:00:12.000 The shadow is about twice that of the black hole’s event horizon, its point of no return. 4 00:00:12.000 --> 00:00:16.000 5 00:00:16.000 --> 00:00:20.000 6 00:00:20.000 --> 00:00:24.000 The orbit of Mercury comes into view. 7 00:00:24.000 --> 00:00:28.000 8 00:00:28.000 --> 00:00:32.000 The Circinus galaxy’s central black hole weighing more than 1 million Suns. 9 00:00:32.000 --> 00:00:36.000 10 00:00:36.000 --> 00:00:40.000 The orbit of Earth comes into view. 11 00:00:40.000 --> 00:00:44.000 The black hole at the center of M32, a satellite of the Andromeda galaxy, weighs more than 2 million Suns. 12 00:00:44.000 --> 00:00:48.000 The black hole at the heart of our own Milky Way galaxy has a mass of some 4 million Suns. 13 00:00:48.000 --> 00:00:52.000 14 00:00:52.000 --> 00:00:56.000 NGC 7727 has two supermassive black holes. The smaller one has a mass of 6 million Suns. 15 00:00:56.000 --> 00:01:00.000 In turn, we pass the orbits of Jupiter, Neptune, and the Kuiper belt. 16 00:01:00.000 --> 00:01:04.000 Now comes NGC 7727’s larger black hole, at more than 150 million solar masses. 17 00:01:04.000 --> 00:01:08.000 The Andromeda galaxy’s monster black hole may weigh up to 140 million Suns. 18 00:01:08.000 --> 00:01:12.000 Radio galaxy Cygnus A is powered by a 2.5 billion-solar-mass black hole. 19 00:01:12.000 --> 00:01:16.000 Now passing the Oort cloud of comets surrounding our solar system. 20 00:01:16.000 --> 00:01:20.000 M87’s black hole, weighing 5.4 billion Suns, is the first to have been imaged directly. 21 00:01:20.000 --> 00:01:24.000 22 00:01:24.000 --> 00:01:28.000 TON 618 lies in an active galaxy so far away its light takes more than 10 billion years to reach us. 23 00:01:28.000 --> 00:01:32.000 The black hole’s mass of 66 billion Suns makes it among the biggest known. 24 00:01:32.000 --> 00:01:36.000 25 00:01:36.000 --> 00:01:40.000 NASA 26 00:01:40.000 --> 00:01:43.467 NASA
