What is the line through the middle of a quasar?

Answer 1

A quasar is a lot like a black hole, in that it was once a star. There are many spikes that do project from the center of the quasar. These are optical spikes. they are like a glare that the telescopes see when they look at a star. if you look at the sun off of a mirror, you can see the same optical spikes from the sun. It is basically a You can also see another line that extends from both sides of the quasar. These lines that you see are actually super heated gas that has been shot out from the center of the quasar. These streams extend many light-years away from the quasar. If you want to learn more, look at some of the Hubble pictures of quasars.

Answer 2

The line through the middle of a quasar is known as the accretion disk. It is a rotating disk of gas and dust that spirals into the supermassive black hole at the center of the quasar. As the material falls into the black hole, it emits intense radiation across the electromagnetic spectrum, giving quasars their bright appearance.
