• Ep. 758: Non-Roving Rovers

  Astronomy Cast Ep. 758: Non-Roving Rovers By Fraser Cain & Dr. Pamela Gay Streamed live on May 26, 2025. Some of our favorite robots are rovers currently roving around the surface of the Moon & Mars. But there’s some pretty tricky terrain out there and engineers are scheming up clever ways to explore other worlds inspired by life that crawls, slithers, hops and flies. As we explore more surfaces and more complex surfaces throughout the solar system, mission teams are designing robot explorers that don't sit still and also don't rove. In this episode, we're going to take a look at the new technologies that are allowing technology to get around.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.  Join at the Galaxy Group level or higher to be listed in our YouTube videos.  Thanks to: BogieNet, Stephen Vei, Jeanette Wink, Siggi Kemmler, Andrew Poelstra, Brian Cagle, David Truog, Ed, David, Gerhard Schwarzer, Sergio Sancevero, Sergey Manouilov, Burry Gowen, David Rossetter, Michael Purcell, Jason Kwong

• 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.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

• 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.

• Ep. 755: Intermediate Mass Black Holes

  Astronomy Cast Ep. 755: Intermediate Mass Black Holes By Fraser Cain & Dr. Pamela Gay Streamed live on May 5, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay. There are stellar-mass and supermassive black holes. But very little evidence of anything in between. Where are all the intermediate-mass black holes that should be the building blocks of the biggest ones? Actually, the science has been accelerating rapidly and we now know of hundreds of them. The question marks in our understanding are slowly getting replaced with data. Let's review what we now know about intermediate mass black holes and their origins.    SUPPORTED BY YOU!

• Ep. 754: K2-18b

  Astronomy Cast Ep. 754: K2-18b By Fraser Cain & Dr. Pamela Gay Streamed live on Apr 28, 2025. You’ve heard the news! Astronomers are reporting the discovery of biosignatures at K2-18b. Is this proof of life or should we all be more skeptical? It's in the news and people are claiming aliens... but is it aliens? Let's see what the data actually says.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon. Join at the Galaxy Group level or higher to be listed in our YouTube videos.
