Astronomers solve the 60-year mystery of quasars -- the most powerful objects in the Universe

"Scientists have unlocked one of the biggest mysteries of quasars -- the brightest, most powerful objects in the Universe -- by discovering that they are ignited by galaxies colliding."

Fascinating and fortunately for us there isn't such an object anywhere near us. It's most unlikely we'd be here if there was?

That's a great 15 minute PBS video about Active Galactic Nuclei (AGNs) and quasars, pulsars, blasars, etc. Lots of detail and pictures by an expert in a very short time. In particular he discusses an AGN that changed directions and is now pointed directly at earth!

Can a quasar escape a black hole once it crosses the event horizon? Is a quasar more powerful than a Gamma Ray Burst? Is it more powerful than the Big Bang?

Great questions for further research!
