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


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


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




The orbit of Mercury comes into view. 



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



The orbit of Earth comes into view. 


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


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



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


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


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


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


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


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


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



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


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