Red, pink, orange, and white galaxies.

Text, Hubble Ultra Deep Field in Infrared. The Hubble Deep Field contains a myriad of beautiful galaxies.

Three small red galaxies are circled in green.

Text, But when astronomers are looking for the most distant galaxies in the universe, they peer past these spirals and ellipticals to search for the tiny, glowing red dots that are the earliest galaxies we can see with Hubble.

The James Webb Space Telescope can see even younger galaxies, in more detail, deeper in the cosmos.
