The galaxy’s light took 13 billion light years to reach Earth, and astronomers estimate that it formed when our universe was only 500 million years old. Although 500 million years is long time for us, it is miniscule compared to the age of our universe, 13.8 billion years.

Astronomers know of only about ten other galaxies that formed so soon after the Big Bang. This newly discovered galaxy, however, is significantly smaller and fainter than the others.
