James Webb Space Telescope Reveals Early Universe's Galactic Evolution.
The James Webb Space Telescope has identified a group of seven baby galaxies dating back to 13 billion years ago, just 650 million years after the Big Bang. These galaxies could potentially grow into one of the biggest conglomerations of mass in the universe, a vast cluster of thousands of galaxies and trillions of stars. Spectroscopic measurements with the Webb telescope confirmed that the seven dots were galaxies and were all equally far from Earth. According to calculations based on prevailing models of the universe, gravity will eventually draw these galaxies together into a massive cluster containing at least a trillion stars.
