[Dramatic music throughout] The Sun is the only object on screen and shrinks as the camera backs away from it. 

[00:00:04.00] 

The 100,000-solar-mass black hole in dwarf galaxy J1601 casts a shadow smaller than the size of our Sun. 

[00:00:08.00] 

The shadow is about twice that of the black hole’s event horizon, its point of no return. 

[00:00:12.00] 

[00:00:16.00] 

[00:00:20.00] 

The orbit of Mercury comes into view. 

[00:00:24.00] 

[00:00:28.00] 

The Circinus galaxy’s central black hole weighing more than 1 million Suns. 

[00:00:32.00] 

[00:00:36.00] 

The orbit of Earth comes into view. 

[00:00:40.00] 

The black hole at the center of M32, a satellite of the Andromeda galaxy, weighs more than 2 million Suns. 

[00:00:44.00] 

The black hole at the heart of our own Milky Way galaxy has a mass of some 4 million Suns. 

[00:00:48.00] 

[00:00:52.00] 

NGC 7727 has two supermassive black holes. The smaller one has a mass of 6 million Suns. 

[00:00:56.00] 

In turn, we pass the orbits of Saturn, Neptune, and the Kuiper belt. 

[00:01:00.00] 

Now comes NGC 7727’s larger black hole, at more than 150 million solar masses. 

[00:01:04.00] 

The Andromeda galaxy’s monster black hole may weigh up to 140 million Suns. 

[00:01:08.00] 

Radio galaxy Cygnus A is powered by a 2.5 billion-solar-mass black hole. 

[00:01:12.00] 

Now passing the Oort cloud of comets surrounding our solar system. 

[00:01:16.00] 

M87’s black hole, weighing 5.4 billion Suns, is the first to have been imaged directly. 

[00:01:20.00] 

[00:01:24.00] 

TON 618 lies in an active galaxy so far away its light takes more than 10 billion years to reach us. 

[00:01:28.00] 

The black hole’s mass of 66 billion Suns makes it among the biggest known.
