Way back in the earliest ages of the universe, the first galaxies were born. Astronomers want to know more about them.

Now that JWST is a working observatory, astronomers are excited to use its data to explore those early epochs. They’re eager to see the most distant objects and — as seems likely — do a rejiggering of the cosmic timeline after the Big Bang.
