This particular galaxy formed sometime at the dawn of the universe, about 700 million years after the Big Bang.
The James Webb Space Telescope made a very special discovery when it observed a galaxy called JADES-GS+53.18343−27.79097 that was growing from the outside in, rather than the usual center-out method.
This means that in this particular “inverted” galaxy, stars are forming on its edges faster than the dense core in its center.
Astronomers had previously suspected that such galaxies might exist in the ancient universe, but they have not been able to observe them until now. However, the James Webb Space Telescope has successfully penetrated the dust and gas clouds and confirmed this theoretical model.
By the way, JADES-GS+53.18343−27.79097 is one of the oldest “inverted” galaxies ever seen, forming sometime at the dawn of the universe, about 700 million years after the Big Bang. It's 100 times smaller than the Milky Way, but it's expanding at an astonishing speed: this galaxy doubles in size in 10 million years, while the Milky Way takes 10 billion years to do so.
Researchers are now studying other galaxies of the same age to understand how they grew to their current size. This discovery may open new horizons for exploring the history of galaxies.
