"the most distant galaxy? 
Hubble Space Telescope continues to surprise with his astronomical discoveries. NASA has just announced that their observations have identified a candidate to become the most distant galaxy known to date. Would find 13,200 million light-years, and we'd be seeing when the Universe was only 480 million years old. The previous record belonged to a galaxy 150 million light-years closer. According to the image, would be a blue compact galaxy of stars, rather small (it would take 100 to give shape to the Milky Way), and very weak. Given this, it concludes that between 480 and 650 million years after the Big Bang, the universe underwent a dramatic increase in the rate of star birth. The observation was made with the Wide Field Camera 3, shortly after being installed on Hubble in May 2009. Astronomers have taken more than a year to discuss the results and make the corresponding analysis. The picture makes clear that the mini galaxy is too young and small to spiral look like ours. Its stars must have formed between 100 and 200 million years ago from gas trapped in a region of dark matter. The new protogalaxy only observable at infrared wavelengths more distant. To go back in time will probably require the participation of Hubble's successor, the James Webb Space Telescope (JWST). (
