The JWST is Forcing Astronomers to Rethink Early Galaxies
Summary by Ground News
The JWST showed us that the early Universe was full of fully-formed galaxies similar to the ones we see today. Astronomers only figured out that there were spiral galaxies in the 1840s when the Earl of Rosse built his gigantic telescope called the Leviathan of Parsonstown. Prior to these observations, we thought that disk galaxies were almost non-existent until the Big Bang.
