Astronomers using the Hubble Space Telescope have found the oldest galaxy to date-- one formed only 480 million years after the Big Bang. That means the universe was organizing itself into something like what we would recognize very early on.
The new galaxy is, so far, singular; only one galaxy has been found that early in time. By contrast, astronomers have so far detected 50 galaxies around the 650 million year mark. In the intervening 170 million years, therefore, things were beginning to pop. That popping soon developed into the unimaginable, explosive process that ultimately created the billions or trillions of galaxies in the universe we know.
