The doomed Hubble space telescope has discoverd a new galaxy so faraway that its light takes 13 billion light years to reach Earth.
"The galaxy we have discovered is extremely faint, and verifying its distance has been an extraordinary challenging adventure," said astronomer Jean-Paul Kneib, of the California Institute of Technology.
The Keck observatory in Hawaii confirmed Hubble's findings, which were made using its "gravitational lensing", based on Einstein's theory of relativity and announced at the yearly meeting of the American Association for the Advancement of Science.
