    the universe

    An example of a galaxy group, in this case the Copeland Septet.
    The universe might be younger than we thought, galaxies' motion suggests

    We think the universe is 13.8 billion years old, but could we be wrong? A new study of bound galaxies offers an unexplored clue.

    • A composite image of the Bullet Cluster, a much-studied pair of galaxy clusters that have collided head on. One has passed through the other, like a bullet traveling through an apple, and is thought to show clear signs of dark matter (blue) separated from hot gases (pink).
      The 1st life in the universe could have formed seconds after the Big Bang

      The first life-forms capable of evolution could have appeared just moments after the Big Bang, a physicist explains.
