AI Summary

NASA’s James Webb Space Telescope has extended the observable universe to the era of the first stars and galaxies, just 150 to 200 million years after the Big Bang. A recent multispectral survey used 150 narrow sightlines across 0.6 square degrees, cataloguing thousands of objects. The data reveal a steep decline in galaxy formation during that early period, indicating that the earliest galaxies were forming rapidly but then slowed dramatically. The study demonstrates JWST’s ability to probe the cosmic dawn and provides a new benchmark for models of early galaxy evolution.
