A telescope orbiting the earth has taken pictures that show galaxies and stars so far away they reveal secrets about the birth of the universe.
The very powerful Hubble telescope stared at a small patch of space over four months and saw the first galaxies from 13 billion years ago.
Because light takes time to reach it, and the galaxies are far away, Hubble can see things in the distant past.
Scientists hope to follow up Hubble's discoveries with new space telescopes.
