๐ญ JWST Just Found a Massive Barred Spiral Galaxy From the Universe's Earliest Epoch
On July 4, an international team reported discovering M1149-BSG-z5, a massive barred spiral galaxy identified using the James Webb Space Telescope โ one of the earliest examples of this galaxy type ever found. Barred spirals like the Milky Way were thought to need billions of years to develop their structure, so spotting one this far back challenges our models of galaxy formation. JWST keeps uncovering fully-formed, complex galaxies at epochs where only simpler structures were expected. Are you still surprised when Webb rewrites the textbook?
