Scientists test the famous physicist’s predictions by calculating the distortion of time and space. Why is the expansion of the Universe accelerating? Even 25 years after its discovery, this remains one of science’s most profound mysteries.

Three ultra-massive galaxies from the early universe, named "red monsters" show star formation happened faster than believed.

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 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.

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).

An international team that includes the University of Bath has discovered three ultra-massive galaxies (‘Red Monsters’) in the early Universe forming at unexpected speeds, challenging current models of galaxy formation.
