Imagine the Universe!

A large disk of gas around a black hole.
Movie (11.4 MB)

Here's a story of a pair of stars called Cygnus X-1
One's a black hole many times the mass of the Sun
With a disk of gas surrounding it, spiralling in
Sucked from the companion star's outermost skin
We see the high-speed flickering as star stuff flies in
A one way trip beyond the event horizon

This video shows the pair of stars Cygnus X-1. One is a black hole with an accretion disk gathering material from the companion star.
