The James Webb Space Telescope (JWST), the largest and most advanced space telescope ever constructed, has been making remarkable discoveries since its launch in December 2021. Among its achievements is the identification of the earliest and most distant galaxies known, which formed just 300 million years after the Big Bang.
When we observe distant objects in space, we are also looking far back in time. This is because the light from these objects takes billions of years to reach our telescopes. Through the JWST, astronomers have detected several of these ancient galaxies, providing us a glimpse of the universe as it appeared shortly after its inception.
Surprising Brightness of Early Galaxies
The data collected by the JWST aligns well with existing theories of cosmology—the study of the universe’s origin and evolution—and galaxy formation. However, these observations have also brought some surprises. Notably, many of these early galaxies are much brighter than expected, challenging previous assumptions about galaxy brightness and activity shortly after the Big Bang. READ MORE...
