James Webb Space Telescope discovers inside-out galaxy from early universe

The James Webb Space Telescope (JWST) has discovered an inside-out galaxy, JADES-GS+53.18343−27.79097, formed 700 million years after the Big Bang. This galaxy grows from the outside in, with rapid star formation at its edges, differing from typical growth patterns. This finding supports theories about early galaxy formation that lacked observational evidence. The discovery, published in Nature Astronomy, is the first of its kind and enhances understanding of galaxy evolution in the early universe. Identified through the JWST's JADES project, the galaxy features a dense core and a disc of gas and dust. It is growing at a rate of doubling in size every 10 million years, much faster than the Milky Way.
