Ep. 546: Weird Issues: Planetary Migration
Before we discovered other planets, our Solar System seemed like a perfectly reasonable template for everywhere. But now we see massive planets close to their stars, which leads you to the question, how does it all get there. Do the planets form in place or do they migrate around?
Ep. 545: Weird Issues: Are comets asteroids or are asteroids comets?
Things used to be so simple. Comets were snowballs from the outer Solar System, and asteroids were rocks from the inner Solar System. But now everything’s all shades of grey. Astronomers have found asteroids that behave like comets and comets that behave like asteroids.
Ep. 544: Weird Issues: Biosignatures
Once again, another place where the Universe is going to make this difficult for us. Proving, once and for all that there’s alien life on another world. It should be straightforward, look for biosignatures, but it looks like there are natural sources that could explain almost any chemical we could hope to search for.
