Today, we are in the Era of Galaxies. Only within the tiniest fraction of cosmic time have humans existed. Today, we see beautiful images of galaxies, stars, nebulae and other structures studded across the sky. We can see that there are patterns to where these structures end up; they are not evenly placed, but instead clump.

Every particle of matter continues to evolve, from the smallest scale of atoms to the largest scale of galaxies. The universe is dynamic. It changes, even now.  

This cosmic scale of time remains hard to comprehend. But science is helping us understand it. And when we look deeper into space, as we are with the James Webb Space Telescope, we see farther back in time — closer to when it all started.
