First post and dont know what to expect

First post of the blog should be about intro and such so here we go. As you read this first posting you should be pondering at the title and ask, what is a Blazar. For those who are not familiar with astronomy a Blazar is basically a compact Quasar. It is a super massive black hole with X-rays shooting out which mimics something like a flashlight from its  center.

Since it only emit X-rays we dont even see this in the sky glowing, so the only way to detect such object is through X-ray telescopes. More interesting thing about the Blazar is that its axis are also tilted like the earth and it rotates at a much faster rate that its noticeable.

Because of its rotating axis its X-ray is only detected when it is in line with the Earth. Therefore only periodically do we detect its X-ray making this something like a light house effect in the sky.
