    Astronomy Cast Ep. 790: Meteorites From Other Worlds By Fraser Cain & Dr. Pamela Gay Streamed live April 17, 2026. Even though humanity has returned samples from a fraction of the worlds in the solar system, the cosmos has delivered many more without us having to lift a finger. Meteorites. We have meteorites from the Moon, Vesta and even Mars! What have we learned about these rocks from other worlds? Space missions to other worlds cost millions to billions of dollars, and if we want to know exactly where space rock samples come from, we need to spend the big bucks for sample return. But, if it's good enough to know "this rock came from somewhere on that world," space offers an amazing delivery system in the form of meteorites. Come learn about the search for, identification, and science of meteorites from other worlds. This show is supported through people like you on Patreon.com/AstronomyCast !!!

    Astronomy Cast Ep. 789: What Happens When a Planet's Star Dies By Fraser Cain & Dr. Pamela Gay Streamed live on Mar 30, 2026. A star like the Sun only lasts about 10 billion years and it becomes a red giant and finally a white dwarf. This is catastrophic for some of the planets, consumed by the expanding red giant star. But most survive. What happens next in the long, slow cooling to the background temperature of the Universe?

    Astronomy Cast Ep. 788: Life's Molecules Form in Space By Fraser Cain & Dr. Pamela Gay Streamed live on Mar 23, 2026. The theory of evolution how life takes on its wildly different forms. But how did life get started in the first place? It appears the Universe has been making life's molecules in space for billions of years, setting up the conditions for life… everywhere? One of humanity's fundamental questions is "where does life come from." We can't answer that question, but we can tell you where some of the stuff of life came from.
