(DESCRIPTION)
Text, at a glance, The first galaxies

View of elliptical and spiral galaxies

Text, Galaxies change in size and appearance over time

Today’s galaxies often have large spiral or elliptical shapes.

Earlier galaxies have less definition

Galaxies shown in a broad view of space are circled and placed in a grid. Each square contains an example of a small round galaxy

Text, And extremely early galaxies often appear as smallish blobs of stars.

The Webb Telescope is helping us understand how the earliest galaxies evolved into the galaxies we see today.
