Oldest galaxy: Astronomers using the Hubble telescope have detected a galaxy that formed just 500 million years after the Big Bang, making it the most distant and oldest galaxy discovered so far.
Astronomers, aiming a ground-based telescope at a target spotted by the Hubble in space, confirm the find as the oldest galaxy so far. Its light was emitted at a time when hydrogen and helium fog still filled the universe.
New Hubble telescope images provide a look at the cosmos when it was just 600 to 800 million years old. Galaxies from this period might have helped transform the universe from dark to light.
