Title: Hubble Reaches the "Undiscovered Country" of Primeval Galaxies

NASA's Hubble Space Telescope has broken the distance limit for galaxies and uncovered a primordial population of compact and ultra-blue galaxies that have never been seen before. The deeper Hubble looks into space, the farther back in time it looks, because light takes billions of years to cross the observable universe. This makes Hubble a powerful "time machine" that allows astronomers to see galaxies as they were 13 billion years ago, just 600 million to 800 million years after the Big Bang.

I wonder how much closer to the Big Bang they can get?   :dunno:

Epoch of Reionisation with either the GMRT or probably more likely when built the SKA.
