Dr. Ranadeep Dastidar -- Astrophysics at the Speed of Light
July 1, 2026 · 1 hr 7 minThe 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…

Dr. Abigail Polin -- Astrophysics Q & A #3
June 1, 2026 · 1 hr 17 minAbigail 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 · 1 hr 6 minThis 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…

Dr. Charles Law -- All the Molecules in Protoplanetary Disks
April 1, 2026 · 51 minJust 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…

Dr. Gurtina Besla -- Dark Matter in the Milky Way
February 1, 2026 · 1 hr 2 minMost of the mass in the universe is invisible. We call it "Dark Matter", and the only reason we know it's there is because we can see how it gravitationally interacts with regular matter. For example, in our own galaxy, Dark Matter…

Dr. Kaitlin Kratter -- Building a Solar System on the Computer
December 1, 2025 · 1 hr 15 minHow did our solar system form? More generally, how does any solar system form? We get some of our answers to these questions by looking at newly-forming planetary systems in the first million years of their lives. But getting a complete…

Dr. Tim Cunningham -- White Dwarfs Sometimes Eat Planets
November 1, 2025 · 1 hr 15 minA white dwarf star is the compact, dense remnant of a once-thriving solar system. Long after the original star has died and turned into a white dwarf, it can still interact with its solar system. We can even see white dwarfs eating up the…

Dr. Merel van 't Hoff -- The Birth of the Planets
October 1, 2025 · 58 minHow did the planets form? What was going on in the first few brief million years of our solar system? And how did it impact what we see in our solar system today? Dr. Merel van 't Hoff takes us on a journey through astrochemistry to…

Dr. Wen-Fai Fong -- The Neutron Star Mash
September 1, 2025 · 43 minWhat kinds of things do neutron stars do? They can smash into each other, producing bright flashes of radiation and strong ripples in spacetime that can be detected across the universe! Or, a neutron star can just be sitting there, and its…
