One of the surprise findings with the James Webb Space Telescope is the discovery of massive galaxies in the early Universe. The expectations were that only young, small, baby galaxies would exist within the first billion years after the Big Bang. But some of the newly found galaxies appear to be as large and as … Continue reading "Three More “Galactic Monster” Ultra-Massive Galaxies Found"

Astronomers are continuing to find ultra-massive galaxies in the early history of the Universe. The three galaxies have a similar mass to the Milky Way, despite being within the first billion years after the Big Bang. These galaxies are forming stars nearly twice as efficiently as lower-mass galaxies or galaxies later on in the Universe. Although they’re still within standard theories of cosmology, they demonstrate how much needs to be learned about the early Universe.
