    Dr. Jeff Gerber -- Let's Talk Stars
    May 1 2026

    This episode we get back to the objects that inspired the whole field of astrophysics -- stars. Those little points of light that first inspired us as children are incredible physics laboratories that we can still use today to learn about plasma physics, turbulence, and nuclear reactions. Dr. Jeff Gerber tells us why he made his career out of studying how stars work, and how much we still have to learn about these giant balls of plasma.

    Dr. Charles Law -- All the Molecules in Protoplanetary Disks
    Apr 1 2026

    Just how much do we know about how the planets formed? How much of this can we learn from getting images of young solar systems? Why does it help to look at the disk using radio waves instead of optical wavelengths? Dr. Charles Law discusses these questions and more as we talk about radio astronomy and the birth of the solar system.
