Si chiama UDFy-38135539, ed è la galassia più lontana mai osservata.
E' stata scoperta da un team di astronomi europei del VLT, e possiede un redshift pari a 8,6, This means that is well 13.1 billion light years and we look at as it was 600 million years after the formation of the universe, in fact we see that is still shrouded in a cloud of primordial hydrogen permeating the universe in the first moments of his life, this is definitely the first galaxy whose light has reached us through the cloud.
This is definitely a huge milestone, because the radiation that reaches us by this object as well as being extremely weak and partly absorbed by the surrounding cloud of hydrogen (or wrapping) the galaxy, but it is a ' huge thrill to know that this dot is shown in the picture above is a galaxy that has quasi visto nascere il nostro vasto universo.
