Hubble Space Telescope shows 5,000 ancient galaxies sparkling

Thousands of distant, primordial galaxies in different shapes and sizes glow in infrared light in a newly released image from the Hubble Space Telescope.

The oldest galaxies are about 13 billion years old, dating from just a few hundred million years after the Big Bang. By looking at those galaxies in ultraviolet light, scientists can discover what chemicals lie inside those galaxies — information that is key to understanding how galaxies form and evolve. But there’s a problem with this method: That primordial ultraviolet light gets absorbed before it can reach us.
