  • Dr. Ranadeep Dastidar -- Astrophysics at the Speed of Light

    Dr. Ranadeep Dastidar -- Astrophysics at the Speed of Light
    Jul 1 2026

    The Theory of Relativity was discovered by Einstein over a century ago, and it tells us how time and space are distorted when moving close to the speed of light. We mere earthlings don't get the opportunity to move that fast, but there are some phenomena in astrophysics that move very fast; more than 99.9999% of the speed of light. Ranadeep Dastidar is a computational modeler who writes code to predict and interpret these "relativistic" phenomena.

    Dr. Abigail Polin -- Astrophysics Q & A #3
    Jun 1 2026

    Abigail Polin is back, and we are doing another astrophysics Q&A! This time, our questions come from a class of third graders in Indiana. You'll be surprised at how some of the simplest questions can lead us down a very complex path!

    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.
