Ep. 623: NEOS: Concern or Nah?
https://youtu.be/AWvd_LN1VL8 Are asteroids dangerous? Just ask the dinosaurs, and they'll tell you a sad story of fiery death. It turns out we're in a shooting gallery of space rock and metal, and somewhere out there there's one with our name on it. Should we be...
Ep. 622: Rocky Moons and Giant Asteroids
https://youtu.be/H8JiaXcGvVI A rock is a rock is a rock, right? Across the Solar System there are giant rocky asteroids and even rockier moons. What's the difference between these two families of objects, and where did they come from? Show Notes | Transcript Show...
Ep. 621: Gas Giants
https://youtu.be/YvV9X_weY1w For the longest time, the only gas giant planets we knew about were Jupiter and Saturn. But now in the age of extrasolar planets, astronomers have discovered thousands of gas giants across almost as many star systems. What new discoveries...
Ep. 620: Why Getting to the Outer Worlds is So Difficult
https://youtu.be/9OVAbDgTgSM Good news! Over the next few years, we're going to see a flotilla of new missions headed to Jupiter and Saturn. Why aren't we seeing more missions to the outer planets, like Uranus and Neptune? It turns out, those places are far away....
Ep. 619: Icy Moons and Dwarf Planets
https://youtu.be/3hJVYAH5wsQ The outer Solar System is far enough from the Sun that water doesn't get blasted away into deep space. In this icy realm, there are many worlds with vast quantities of water ice. Today let's look at the icy outer moons and dwarf planets....
Ep. 618: Ice Giants
https://youtu.be/1L2FdcC_vsA We're learning more and more about the outer planets of the Solar System. Uranus and Neptune are ice giants, filled with water and other volatiles that we'd consider ice if it was here on Earth. What's inside these worlds, and what could...
Ep. 617: Hangout-a-thon Episode 2 – Crowdfunding Science
https://youtu.be/La5ZNRro6zM Funding for basic science has always been tricky business, coming mainly from universities, government, companies, or wealthy individuals, but who knows how many fascinating discoveries were never made because of a lack of funding? We now...
Ep. 616: Hangout-a-thon Episode 1 – The Great Observatories
https://youtu.be/ZGJesDhTVpw You're familiar with the Hubble Space Telescope, of course, but it's just one of NASA's Great Observatories. After Hubble came three more incredible observatories, each greater than the last. Together, they would fill in almost the entire...
Ep. 615: Planet 9
https://youtu.be/r4wvIIWLfcI After Pluto lost its planethood, we were down to 8 planets. But there's growing evidence of another world (or worlds) out beyond the orbit of Pluto. Is Planet 9 out there and how will we find it? Could there even be a Planet 10? Show Notes...
Ep. 614: Centaurs, Comets and Asteroids
https://youtu.be/Rik2atXaE6E There are asteroids and there are comets. But there's an entirely separate class of objects called centaurs. But instead of half-human, half-horse, imagine an object that's half comet, half asteroid but 100% interesting. Show Notes |...
Ep. 613: Pluto’s Demotion: 15 Years Later
https://youtu.be/qreJoGzZx-4 It's been 15 years since Pluto was kicked out of the planet club. It also happens to be the topic of our very first episode of Astronomy Cast more than 600 episodes ago. Are there any updates? Does Pluto have a chance of regaining...
Ep. 612: Update: SETI, METI (and WETI)
https://youtu.be/hMULAbRA8YQ Last week we talked about the various ways that astronomers could detect the presence of intelligent civilizations by observing technosignatures. This week we'll give you an update on the state of searching for extraterrestrials. This...
Ep. 611: What is Required to Confirm Alien Life: Intelligence Edition
https://youtu.be/64_YM6PgnA0 Last week we talked about what it's going to take to confirm basic biological life across the Solar System and the Milky Way. This week, we'll discuss what it's going to take to detect intelligent life out there in space. Show Notes |...
Ep. 610: What is Required to Confirm Alien Life: Non-sentient Edition
https://youtu.be/0rtBR5WUx6E Are we alone in the Universe? It's one of the biggest scientific questions we can possibly ask. And yet, with rovers on Mars, missions planned to visit Europa and Ganymede. Powerful telescopes able to detect the atmospheres of exoplanets,...
Ep. 609: The Benefits of Volcanoes
https://youtu.be/q9ycfi0lbGo Volcanoes can be some of the worst natural disasters we can experience here on Earth, but life wouldn't even exist without them. What are volcanoes good for anyway? Show Notes | Transcript Show Notes See the First Images NASA’s Juno Took...
Ep. 608: NASA Perseverance – The First 100 Days
https://youtu.be/A3cfWlxF4YI As you all know, Pamela refuses to talk about any missions which aren't actually doing science. Well, Perseverance has crossed the line, from fantasy to an actual working rover, scooping regolith and yeeting helicopters. What has the rover...
Ep. 607: InSight and Marsquakes
https://youtu.be/9Hd_7NacOgU Mars is cold and dead today, but the massive volcanoes tell us what the planet used to be like, millions and even billions of years ago. But how volcanically active is the planet today? That's what NASA's Mars InSight lander is there to...
Ep. 606: Time Dilation – Skipping Through Time
