The Hubble Space Telescope has discovered a galaxy which astronomers believe is the oldest galaxy ever discovered.
The astronomers believe that the galaxy is over 13 billion years old, and that it was formed around 500 million years after the big bang. The galaxy is a relatively small galaxy, like the Milky Way, and it is also growing very quickly. The images were initially published in Nature journal.
