Ep. 684: Too Big, Too Soon: Massive Early Galaxies Defy Expectations

Astronomy Cast Ep. 684: Too Big, Too Soon: Massive Early Galaxies Defy Expectations by Fraser Cain & Dr. Pamela Gay Streamed live on May 29, 2023. One of JWST's top jobs is to peer deeper into the Universe than ever before, watching as the first galaxies came together. Surprisingly, astronomers found galaxies that seemed much more mature than expected, much earlier than it was believed possible. What's going on and what does it mean for cosmology?
