James Webb telescope confirms inside-out galaxy formation in early universe

The James Webb Space Telescope has discovered an "inside-out" galaxy, named JADES-GS+53.18343−27.79097, dating back to just 700 million years after the Big Bang. This galaxy is about 100 times smaller than the Milky Way and shows rapid star formation on its outskirts. Previous models predicted that early galaxies would form inside-out, but scientists lacked the tools to confirm this. The JWST's advanced capabilities allowed researchers to observe this unique galaxy, confirming their theoretical predictions published on October 11 in Nature Astronomy. The galaxy has a dense core and a surrounding disc of gas and dust, with stars forming rapidly. Researchers plan to search for more galaxies like this one to better understand how galaxies evolved in the early universe.
