HUDF-JD2

HUDF - JD2 is a galaxy that has been using the infrared camera on the Hubble Space Telescope Hubble Ultra Deep Field found in. She is eight times larger than our Milky Way and located about 12.8 billion light years ( redshift 6.5 ). Thus we see an image of this galaxy from a time shortly after the Big Bang, when she was only a few hundred million years old.

The size of the galaxy and its age, the astronomers puzzled, since you been with current theories of their formation can not explain. You must have grown much faster than previously thought and then suddenly have set the star formation.
