    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.

    Ep. 787: Evolved Stars (They're not dead yet!)
    Mar 23 2026
    Astronomy Cast Ep. 787: Evolved Stars (They're not dead yet!) By Fraser Cain & Dr. Pamela Gay Streamed live on Mar 16, 2026. Main sequence stars spend most of their time being… normal. Fusing hydrogen into helium in their cores. Producing radiation. But as their stockpiles of hydrogen run out they switch to other fuels, starting to climb the ladder of the periodic table of elements. And this is when things get weird. As we get more and more observations of the cosmos, our understanding gets more detailed. In this episode we look at all the ways a star can die and the updates that we've learned in the past 20 years of Astronomy Cast.
