James Webb May Have Found One of the Universe’s First Galaxies

About this episode

This episode discusses the discovery of LAP1-B, one of the universe's first galaxies, using the James Webb Space Telescope.

Using the James Webb Space Telescope, astronomers discovered LAP1-B, one of the most chemically primitive galaxies ever observed, appearing just 800 million years after the Big Bang. By using Gravitational Lensing to magnify its light, researchers found extremely low amounts of heavy elements and possible evidence of elusive Population III Stars, the first generation of stars in the universe. Scientists believe the galaxy is embedded within a massive halo of Dark Matter, offering a rare glimpse into the earliest stages of cosmic evolution and galaxy formation.
