The disk of A1689B11 is cool and thin, yet it produced stars at thirty times the rate of the Milky Way. With a lookback time (the difference between the age of the universe now and the age of the universe at the time light left the galaxy) of 11 billion years in the concordance cosmology, A1689B11 is forming 2.6 billion years after the Big Bang. And its present comoving distance is about 19.4 billion light-years from the Earth. It is one of the
