Animation of Black Hole in Elliptical Galaxy
This artist's animation depicts a journey into the center of an elliptical galaxy. After traveling past stars in the outer part of the galaxy, the supermassive black hole located at the bright center of the galaxy becomes visible. This black hole is surrounded by hot gas shown in red and yellow, which acts as fuel for the black hole engine. Power generated by the engine flows away from the black hole via jets of high-energy particles.
In addition, I managed to check out a documentary [Part 1, Part 2] on YouTube (starring Sam Neill) and produced by BBC (regarding black holes). Very educational.
