An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang.

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

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,

Recent observations by the James Webb Space Telescope (JWST) have uncovered a trio of ultra-massive galaxies, each nearly as massive as the Milky Way, formed within the Universe's first billion years.

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.

In the dark reaches of the early universe, three monstrous galaxies were already lurking — a mere billion years after the Big Bang. These galaxies, nearly as massive as our own Milky Way, were just uncovered by an international team led by the University of Geneva (UNIGE).
