    Ep. 723: Exoplanets by the Numbers
    Jun 17 2024
    Astronomy Cast Ep. 723: Exoplanets by the Numbers By Fraser Cain & Dr. Pamela Gay Streamed live on Jun 10, 2024. Astronomers have discovered thousands of exoplanets, revealing entirely new types of worlds that we just don’t have in the solar system. It’s enough to start getting a rough sense of what kinds of planets are out there. What’s the big picture? This Episode is made possible thanks to our Patrons on Patreon.

    Ep. 722: Weather on Exoplanets
    Jun 10 2024
    Astronomy Cast Ep. 722: Weather on Exoplanets By Fraser Cain & Dr. Pamela Gay Streamed live on Jun 3, 2024. Here’s a familiar question: How’s the weather? We’re familiar with the weather on Earth and telescopes and missions are watching the weather on other planets in the Solar System. But for the first time in history, astronomers can now answer that question for exoplanets, located light-years away from us. This Episode is made possible thanks to our Patrons on Patreon.

    Ep. 721: Rogue Planets
    May 27 2024
    Astronomy Cast Ep. 721: Rogue Planets By Fraser Cain & Dr. Pamela Gay Streamed live on May 20, 2024. Most of the exoplanets we’ve found are around stars, where they belong. But a few have been found free-floating in interstellar space. The evidence is growing that there are a lot of them out there, maybe even more than planets with stars. How do they form and how can we learn more about them?

    Ep. 720: Galaxy Series - Elliptical Galaxies
    May 20 2024
    Astronomy Cast - Ep. 720: Galaxy Series - Elliptical Galaxies by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 30, 2024. Our galaxy series continues with elliptical galaxies. Unlike other types, these are large, smooth with very few distinguishing features. They’re filled with red and dead stars, a clue to their evolution.

    May 13 2024
    Astronomy Cast Ep. 719: Galaxy Series - Spiral Galaxies by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 30, 2024. Our galaxy series continues, on to spiral galaxies. In fact, you’re living in one right now, but telescopes show us the various shapes and sizes these galaxies come in. Thanks to JWST, we’re learning how these spirals got big, early on in the Universe.

    May 6 2024
    Astronomy Cast Ep. 718: Galaxy Series - Dwarf Galaxies by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 30, 2024. It’s time to begin a new mini-series, where we’ll look at different classes of galaxies. Today, we’ll start with the dwarf galaxies, which flock around larger galaxies like the Milky Way. Are they the building blocks for modern structures?

    Astronomy Cast Ep. 717: Understanding the Ages of Distant Cosmic Objects by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 22, 2024. How old is that star? That planet? That nebula? Figuring out the ages of astronomical objects is surprisingly challenging. Fortunately, astronomers have developed a series of techniques they can use to work out the ages of stuff.

    Astronomy Cast Ep. 716 - The God**** Particle - Remembering Peter Higgs by Fraser Cain & Dr. Pamela Gay Streamed live on Apr 15, 2024. Last week, we learned about the death of Peter Higgs, a physicist and discoverer of the particle that bears his name. The Large Hadron Collider was built to find and describe the particle. Today, we’ll look back at the life of Peter Higgs and his particle.
