Exploring the Cosmic Frontier with JWST

The James Webb Space Telescope (JWST) launched in December 2021, first started collecting data in June 2022, and is already revolutionizing our understanding of the distant Universe. With it’s large segmented mirror, and optimization for infrared wavelengths, JWST was designed to detect and characterize some of the first galaxies to form in our universe and investigate how galaxies then evolve over the age of the Universe to the present day. In this talk, I will present how JWST has pushed our cosmic frontier beyond what was previously possible and highlight what we have learned from the first year of extragalactic deep surveys and their implications for our understanding of the early universe. I will also present some of the first results from the largest Cycle 1 general observer program, COSMOS-Web.
