  • Dr. Wen-Fai Fong -- The Neutron Star Mash
    What 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 magnetic field might suddenly shift and produce a dramatic burst of radio waves! But mainly, neutron stars are super-dense and super-complicated, giving us a probe of fundamental physics in its most extreme limits. Dr. Wen-Fai Fong tells us all about how we can learn more!

  • Dr. Daniel D'Orazio -- The Black Hole Shuffle
    Just how big can black holes get? Well, they can get super-massive! That is, millions to billions of times as massive as the sun. How do we know this? We've detected these supermassive black holes at the centers of galaxies in a number of ways, and Dr. Daniel D'Orazio has been leading the way in figuring out new ways we can detect more, especially if it's not one but two black holes orbiting one another in a binary system.

  • Dr. Abigail Polin -- Astrophysics Q & A
    In this week's episode, Dr. Abigail Polin joins us to answer your questions from the internet, on a variety of topics tangentially related to astrophysics! Questions range from the basic and fundamental to the obscure and weird. Answers are totally unprepared and rambling. Our guests this week are Dr. Abigail Polin, PLUS an extra-special mystery guest!

  • Dr. Andrea Derdzinski -- How do we see black holes?
    A black hole is so dense, its gravitational field prevents anything from escaping, including light. You would think that would make them the "blackest" things in the universe; how in the world do we know they are there? Dr. Andrea Derdzinski tells us about how we detect black holes, either due to the gravitational waves they produce, or due to their interaction with material orbiting around them, which paradoxically can make them some of the brightest objects in the universe.

  • Dr. Jared Goldberg -- Does Betelgeuse have a Betelbuddy?
    Up in Orion's shoulder sits Betelgeuse, a supergiant star near the end of its life. The surface of Betelgeuse has been roiling and pulsing for centuries, as long as humans have recorded its modulated luminosity. Dr. Jared Goldberg is a postdoctoral research fellow at the Center for Computational Astrophysics in the Flatiron Institute in New York City. Dr. Golberg has been developing computer models for Betelgeuse to help understand and interpret its oscillations over time.
