Joining us in this episode is physicist and astrophysicist Marco Castellano. Marco is a researcher at Osservatorio Astronomico di Roma-INAF, where he investigates galaxy formation – specifically looking at the early galaxies that formed right after the Big Bang.  Our universe is estimated to be 13.7 billion years old, and the James Webb Space Telescope has been using infrared technology to explore the ancient history of our cosmos. This revolutionary device is illuminating an array of mysteries that astronomers have been guessing at for centuries…  Tune in now to hear Marco discuss: What the James Webb Space Telescope is telling us about extragalactic origins. When the first galaxies were formed, and why it took so long for them to do so following the Big Bang. What the very first stars may have looked like. We are living in an exciting time for astronomy, and Marco is among the integral researchers that are at the forefront of these fascinating discoveries.
