At the edge of the visible universe


At the edge of the visible universe almost the farthest galaxies are more than 13,000 million light years away. Their light has taken that long to reach us. This means that as we were more than 13,000 million years, only 500 million years after the Big Bang. Therefore, more distant galaxies are also the oldest in the Universe. The most distant galaxy discovered to date is the Abell 1835 IR1916. It is located behind the cluster Abell 1835, in the constellation Virgo. It was discovered in the year 2007 by European scientists. This is 13,200 million light years away and each time more.
