James Webb telescope confirms the earliest galaxy in the universe is bursting with way more stars than we thought possibleThe light from the most distant galaxy in the known universe suggests that there's something off about our current cosmological models, a new James Webb Space Telescope study finds. The explanations remain elusive.

James Webb telescope finds carbon at the dawn of the universe, challenging our understanding of when life could have emergedThe James Webb Space Telescope has found carbon in a galaxy just 350 million years after the Big Bang. That could mean life began much earlier too, a new study argues.
