Using the James Webb Space Telescope (JWST), astronomers have uncovered previously unseen structures and activity in Jupiter’s atmosphere above the Great Red Spot, caused by powerful atmospheric gravity waves. These findings challenge the previously held assumption that the region above the Great Red Spot was relatively uninteresting and offer insights into the complex dynamics of Jupiter’s atmosphere.
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.
Astronomers have detected carbon in a galaxy dating back to just 350 million years after the Big Bang, the earliest discovery of an element other than hydrogen in the universe. This challenges the assumption that carbon formed billions of years later and suggests that life could have emerged much earlier than previously thought.
Using observations from the James Webb Space Telescope (JWST) and the Hubble Space Telescope, astronomers have discovered two of the earliest and most distant galaxies in the known universe. Named JADES-GS-z14-0 and JADES-GS-z14-1, these galaxies date back to just 300 million years after the Big Bang. They are also unusually large for such an early time in cosmic history, challenging our understanding of how galaxies formed and evolved in the early universe.
