NASA's telescopes reveal that small galaxies ended the early universe's "dark ages" by producing light to disperse hydrogen gas.

These dwarf galaxies ignited, producing enough light to burn away the fog of hydrogen gas that previously absorbed most of the light, ultimately helping to create the transparent universe we see today.
