The James Webb Space Telescope (JWST) has discovered five proto-globular clusters within the Cosmic Gems arc, a galaxy formed just 460 million years after the Big Bang. These clusters, which are incredibly dense and formed with high efficiency, are among the earliest ever observed, offering a glimpse into the formation of stars and galaxies during cosmic dawn.
Results for: Cosmic Dawn
Astronomers have made a groundbreaking discovery, observing two active black holes merging at their farthest distance ever, just 900 million years after the Big Bang. This marks the first time two luminous supermassive black holes have been spotted during cosmic dawn, the early period of the universe. The discovery, made using the Subaru Telescope’s Hyper Suprime-Cam, provides valuable insights into the evolution of the universe and the formation of supermassive black holes.
