The findings suggest that the formation of stars in the early universe was much quicker than previously thought.

Researchers using the James Webb Space Telescope have discovered three massive galaxies from the early universe, revealing them to be as massive as the Milky Way and forming stars with surprising efficiency.

A group of international astronomers have discovered three mysterious, ultra-massive galaxies in the early universe. The galaxies – systems of stars, gas, dust, and dark matter – appear in a view from NASA’s James Webb Space Telescope like creepy, blood-red glowing eyes. They get their striking color from their extreme amount of dust.

The galaxies, each as vast as the Milky Way, are baffling because most scientific models for galaxy evolution suggest processes that would have been slow and inefficient, said Stijn Wuyts, an astronomer from the University of Bath in the United Kingdom.

An international team of astronomers has identified three ultra-massive galaxies—each nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang. The discovery is surprising because it indicates that the formation of stars in the early Universe was far more efficient than previously thought,

The James Webb telescope has spotted three gigantic "red monster" galaxies that were spawned soon after the Big Bang. They're so large they could rewrite the laws of galactic evolution.
