The Hubble Space Telescope shows 5,000 ancient galaxies glistening like confetti

Thousands of distant, primordial galaxies of various shapes and sizes shine in infrared light in a recently published image from the Hubble Space Telescope.

The oldest galaxies they are about 13 billion years old and date back only a few hundred million years Big Bang. By looking at these galaxies in ultraviolet light, scientists can discover what chemicals are inside those galaxies – information that is key to understanding how galaxies form and evolve. But there is a problem with this method: that primordial ultraviolet light is absorbed before it reaches us.
