Episode notes

With the tools we have now, it's very difficult to tell what's in a planet's atmosphere unless it's not just distance. But if we get better instruments that we want to build in the future, we'll be able to greatly expand the number of planets we can do that for.

Can there be life on planets without magnetic fields? Neil deGrasse Tyson and comedian Chuck Nice discuss exoplanets, extraterrestrials, and answer extraordinary questions from our fans with astrobiologist, David Grinspoon.
