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.
