The jet from Cygnus X-1 -- a black hole orbiting a massive blue star -- is 10,000 times as powerful as the whole Sun! (That's 10^37 ergs/sec.) And it's moving at 50% the speed of light.

You have moved into a parallel reality, a precursor to our own and smashed all the butterflies you found there. You have taken not just comfort, but life itself. You are not just a destroyer of worlds. You are the antithesis of all that is not only good, but merely possible.

Of course! Have you ever heard of a newtononomic chair?

Nitpicking I think it should be "at right" in the Alt text.

By analyzing how the wind bends the jet, the astronomers were able to calculate how much power is in the jet. Very crafty.
