Astronomers using the James Webb Space Telescope have identified a massive galaxy that shows no rotation, formed less than 2 billion years after the Big Bang. The finding challenges existing models of galaxy evolution.
The galaxy, known as XMM-VID1-2075, contains several times as many stars as the Milky Way and has already ceased forming new ones. Lead researcher Ben Forrest from the University of California, Davis, described the absence of rotation as surprising and unexpected for such an early object.
