Galaxies in the universe today have come a long way from the first structures that emerged after the Big Bang. Galaxies like our own Milky Way are composed of hundreds of billions of stars these days, but things weren't always like this.
Now, researchers using NASA's James Webb Space Telescope (JWST) have peered back deep into our cosmic history, just 700 million years after the Big Bang, which occurred about 13.8 billion years ago. They studied an infant galaxy from that epoch to see how star formation differs from that of galaxies in the universe today.
