In this episode of Plain Talk Science, we explore the groundbreaking discovery of two luminous galaxies confirmed to exist just 300 million years after the Big Bang. Using data from the James Webb Space Telescope (JWST), researchers have identified galaxies at a redshift of 14, challenging our understanding of early galaxy formation. We break down what this discovery means for our view of the universe, how these galaxies formed so early, and why they’re far brighter than expected. Tune in for an exciting deep dive into cosmic history and the latest in cutting-edge space science!
