The James Webb Space Telescope: Discoveries and Puzzles from the First Year

The James Webb Space Telescope (JWST) has revolutionized our understanding of the Universe, allowing astronomers to study galaxies that were forming just after the Big Bang during so-called "Cosmic Dawn." There have been many surprises that are challenging theories of galaxy formation and evolution, including the discovery of unexpectedly bright galaxies and supermassive black holes in the very young Universe. Dr. Allison Strom will review what astronomers have learned from the first year of JWST observations, including work by her own team, who have recently uncovered evidence of rarely seen elements like nickel in galaxies that were forming more than ten billion years ago.
