Pictures of the Early Universe (featuring Dr. Alan Dressler)

Dr. Alan Dressler discusses the James Webb Space Telescope and its ability to see galaxies in the throes of birth 13 billion years ago. The telescope takes pictures of galaxies with extreme sensitivity to infrared light, allowing astronomers to explore the earliest moments of the universe. The team found that galaxies were born with explosive bursts of star formation, unlike anything seen before. New episodes of Looking Up release every other Friday!
