From the present day all the way to less than 400 million years after the Big Bang, we're seeing how the Universe grew up like never before.
Taking us beyond the limits of any prior observatory, including all of the ground-based telescopes on Earth as well as Hubble, NASA's JWST has shown us the most distant galaxies in the Universe ever discovered. If we assign 3D positions to the galaxies that have been sufficiently observed-and-measured, we can construct a visualized fly-through of the Universe, as the CEERS data from JWST enables us to do here.

Key Takeaways
- With our own naked eyes, we can only see the stars and nebulae of the Milky Way and a few other nearby galaxies: all within our gravitationally bound Local Group.
- But thanks to a variety of observatories, including the Sloan Digital Sky Survey, Hubble, and now JWST, we can see what the Universe is like both near and far.
- With their newest visualization based on CEERS data taken with JWST, we can now "fly through" the Universe all the way back to when it was just 3% of its current age. Here's what it looks like!
