How the Universe Created the Conditions for Life | Astrobiology Series Part III

In Part 3 of the Dr. Starkid astrobiology series, Dr. Dakotah Tyler traces the history of the universe from the Big Bang to the formation of worlds capable of supporting life. Expect to learn about the three major lines of evidence for the Big Bang, Big Bang nucleosynthesis, the cosmic microwave background, the first stars, and how stellar explosions created the heavier elements needed to build planets. The episode also covers planet formation, migrating gas giants, the Grand Tack model, why Mars may be so small, how Earth got some of its water, the giant impact that formed the Moon, and why icy moons such as Europa may contain oceans beneath their surfaces. This series is adapted from astrobiology courses taught at UCLA and Pomona College. Hosted by Dr. Dakotah Tyler. Lead with curiosity.
