• Ep. 747: Rogue Planets

  Streamed live on Mar 10, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay Most planets orbit stars. That’s the rule, right? Well, maybe not. In fact the vast majority of planets could be floating freely through the Milky Way. Today we’re gonna talk about rogue planets. Sometimes planets just go rogue. Let's learn about planets living free from stars.    Show Notes: Earth's Dust Storms Mars' Global Dust Storms Dust Storms on Titan Potential Dust Storms on Exoplanets   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

• Ep. 746: Dust Storms

  Astronomy Cast Ep. 746: Dust Storms By Fraser Cain & Dr. Pamela Gay Streamed live Feb 24, 2025. We have dust storms on Earth and of course the famous dust storms on Mars. There are even dust storms on Titan. What causes these storms and how do they work differently on the worlds in the solar system. But what about the exoplanets? The bane of solar panels, humans, and robots, dust storms have a way of picking up steam (or at least dust) all over the solar system.   Hosted by: Fraser Cain and Dr. Pamela L.

• Ep. 745: How We Know If Asteroids Will Attack

  Astronomy Cast Ep. 745: How We Know If Asteroids Will Attack By Fraser Cain & Dr. Pamela Gay Streamed live Feb 20, 2025. I’m sure you’ve heard the news, asteroid 2024 YR4 has a tiny chance of hitting Earth in 2032. How do astronomers discover these dangerous asteroids, measure their future impact risk and track the changes over time? When should we panic? New asteroids are found every day, and every day we learn that those asteroids don't have any murderous intentions. But how do we learn that? In this episode we dig into asteroid orbital determination. Hosted by: Fraser Cain and Dr. Pamela L. Gay   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

• Ep. 744: Lunar Time

  Astronomy Cast Ep. 744: Lunar Time By Fraser Cain & Dr. Pamela Gay Streamed live on Feb 10, 2025. What time is it? OK, fine, what time is it on the Moon? The Moon orbits the Earth, so it doesn’t fall into a specific time zone. Also, there’s lower gravity on the surface of the Moon, which changes the rate that clocks tick. Well… It’s time to introduce Lunar Time.  When are you when you are on the Moon? Researchers are putting together definitions! Hosted by: Fraser Cain and Dr. Pamela L.

• Ep. 741: Technosignatures

  Astronomy Cast Ep. 741: Technosignatures By Fraser Cain & Dr. Pamela Gay Streamed live on Jan 20, 2025. As humanity developed more advanced technology, we’re having a larger effect on our environment. The more we do, the more we could be detectable. And this gives us ideas on how we could detect other civilizations, even if they don’t realize we’re watching.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.
