Three Years of JWST Unveiling the Universe’s Greatest Mysteries
On this day three years ago, the James Webb Space Telescope (JWST) launched into space, marking the beginning of a new era in cosmic exploration. Despite taking three decades to build, JWST has, in just three years of operation, revolutionized our understanding of the universe and uncovered mysteries that challenge established scientific models.
Peering Into the Early Universe
One of JWST's most significant achievements is its ability to peer back in time to the early universe. Using its powerful infrared capabilities, it has identified galaxies that formed when the universe was just 300 million years old.
These early galaxies, surprisingly massive and bright, lack the dust expected from star formation, leaving scientists puzzled. Were their stars collapsing without supernova expl...
