| 12/22/25 |  Ep. 775: The Hydrogen 21-cm Line | Astronomy Cast Ep. 775: The Hydrogen 21-cm Line By Fraser Cain & Dr. Pamela Gay Streamed live on Dec 15, 2025. Atomic hydrogen is the raw material for stars, but there's a problem. It's cold & dark, but it can do a very rare trick, releasing a photon in a very specific wavelength, known as the 21 centimeter line. And thanks to this wavelength astronomers have mapped out star forming regions across the Milky Way, the Universe and into the Dark Ages! This forbidden transition of Hydrogen has led to the mapping of galaxy rotation, a cool classroom application of quantum mechanics, and weirdly no Nobel prize. In this episode, Fraser and Pamela take a look at this line's out-of-proportion awesomeness!

| 6/30/25 |  Ep. 761: It's Here! The Vera Rubin Observatory | Astronomy Cast Ep. 761: It's Here! The Vera Rubin Observatory By Fraser Cain & Dr. Pamela Gay Streamed live June 25, 2025. The time has come. The mighty Vera Rubin Observatory has finally come on line and delivered its "first light" images. And by Pamela's rules that means we get to talk about it! So let's do that! After decades of waiting, we have images from Vera Rubin Observatory! SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

| 6/16/25 |  Ep. 759: The Commercial Space Program | Astronomy Cast Ep. 759: The Commercial Space Program By Fraser Cain & Dr. Pamela Gay Streamed live on Jun 9, 2025. Humanity has turned its focus back to the Moon, sending a fleet of spacecraft to the lunar surface. Some are run by the government, but there's a whole new group of commercial landers bearing instruments to the lunar surface. Is this the future of lunar exploration? Space used to be a place occupied by government-funded and military missions, but today, we're seeing the rise... and fall (somersault, crash, and explosion) of missions with commercial design and funding. Let's talk about how this is good, bad, and maybe just too soon. SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

| 5/26/25 |  Ep. 757: CubeSats | Astronomy Cast Ep. 757: CubeSats By Fraser Cain & Dr. Pamela Gay Streamed live on May 19, 2025. Computers are getting smaller, faster and more capable, which has enabled an entirely mew class of satellites: CubeSats. A mission small enough that you can hold it in your hands, and yet powerful enough to even travel to other planets and send messages home. Every year, our electronics seem to get smaller and more powerful, with today's smart watches being more fully featured than the computers Pamela and Fraser had as little kids. These tiny processors, sensors, and transmitters are allowing tiny satellites with powerful functionality, and today we take a look at how this is changing space exploration.

| 5/19/25 |  Ep. 756: SphereX | Astronomy Cast Ep. 756: SphereX By Fraser Cain & Dr. Pamela Gay Streamed live on May 12, 2025. NASA's newly launched SphereX mission is up & operational and has completed its initial checkout and "first light". Everything looks good! And now it's starting its science operations. And that's good enough for Pamela! And THAT means we can talk about it. So let's do that! There's a new space telescope in town (or at least in LEO). Let's check out what it's looking at and looking to do. SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.
