Hubble

The Hubble space telescope, launched in 1990 filled with errors when it was put up in space. The problem was getting images from far distance was a total blur and this was cause by the assembly and the mirrors itself. The mirrors were the best hyperbolic mirrors for its time but its precision was off by some nano meters which cause a huge error. It was not till 94' where a service mission was launched to fix the problem and fixes the problem, and the rest was history. Given the background history of Hubble lets see what kind of discoveries it comes up with today.

Recently the Hubble discovered the furthest distant super nova explosion yet. The super nova is type la, it is estimated to be 9 millions years old since the further you look the more backward you would go in time. Looking at this kind of super nova back in time helps bring in evidence of dark energy in the stage of the universe where it starts to rapidly expand. This super nova dubbed SN Primo (the picture above), is part of a three year, ongoing survey by the Hubble to detect far away remote super nova such as this. Later on depending on its stability it would be used as a marker to track other further stars.

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.
