CRISTAL, an ALMA Large Program, observed 39 typical star-forming galaxies selected to represent the main population of galaxies in the early universe.

Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.

If early galaxies functioned in the same way, Wold said, they would have generated enough light to reionize the hydrogen fog and make the universe transparent.
