Quasars. A topic that once encouraged me to take astronomy in college.

Always had a fascination with them. Still much is to be known about them, yet somethings have become more known than others. Even from my college days long long ago in 1984.

Refer to this image when the video refers to accretion disk. Image an artist rendition of one of the furthest known quasar.

Hopefully some day, in a million years, this might become a real image.
