JWST finds a Milky Way twin born shockingly early in the Universe
SMRTR summary
NASA's James Webb Space Telescope discovered Alaknanda, a fully-formed spiral galaxy with two prominent arms that existed just 1.5 billion years after the Big Bang, when the Universe was only one-tenth its current age. This galaxy challenges current theories about cosmic evolution because such organized structures were thought to require billions of years to develop, forcing astronomers to rethink how quickly galaxies can form in the early Universe.
