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.

Astronomy Cast Ep. 760: What to Look For This Summer By Fraser Cain & Dr. Pamela Gay Streamed live on Jun 16, 2025. It’s almost time for our annual summer hiatus, but before we go, we wanted to direct you towards all the fun and space stuff we’ll be enjoying this summer. We’ve got meteor showers, planets, rocket launches, TV shows, movies! Here’s what’s good. In a couple of weeks, we'll go on hiatus, but we want to make sure you are ready for stuff we can anticipate happening.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

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.

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

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.

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.

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!

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.

Astronomy Cast Ep. 753: Why is the Moon's South Pole So Interesting? By Fraser Cain & Dr. Pamela Gay Streamed live on Apr 21, 2025. I’m sure you’ve heard that all eyes are on the Moon’s southern pole. This is where various  NASA and Chinese missions are targeting. What makes this region so special and what are the special challenges that explorers will face. From TV shows to real-world missions, it seems like everyone just wants to explore the Moon's South Pole. But why?

Astronomy Cast Ep. 752: Should We Go to the Moon or Mars Next? By Fraser Cain & Dr. Pamela Gay Streamed live on Apr 16, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay There is an ongoing debate on where NASA should go next with humans: to the Moon or Mars. (Or maybe an asteroid or one of Mars’ moons). We are on the verge of sending humans back to the Moon. At the same time others would prefer we focus our exploration on Mars. It’s a tough choice because there are costs and benefits to both. Let’s try to give this conversation some nuance. Let's discuss the reasons for each of these worlds.   SUPPORTED BY YOU! This Episode is made possible thanks to our Patrons on Patreon.
