astro[sound]bites · Episode 110: Bayesian Biosignatures

Apply to join us as a co-host! https://astrosoundbites.com/recruiting-2025 This week, Shashank, Cole and Cormac discuss a concept that has come up on many an ASB episode past: Bayesian statistics. They start by trying to wrap our heads around what a probability really means. Cole introduces us to a recent and attention-grabbing paper on a potential biosignature in the atmosphere of an exoplanet, with lots of statistics along the way. Then, Cormac brings up some counterpoints to this detection. They debate what it would take—statistically and scientifically—for a detection of biosignatures to cross the line from intriguing to compelling.

astro[sound]bites · Episode 89: Extremely Emotional Exoplanets

In this episode, we hear about Kiersten and Will’s epic adventures in both hemispheres! Both Kiersten and Will watched the eclipse that passed through North America on April 8, 2024 and are still buzzing with excitement. Kiersten tells us about a recent paper that explores why planets might act so indecisive about sitting between being a super-Earth or mini-Neptune. Will’s astrobite describes a similarly chaotic exoplanetary tale about a very slow moving planet which “came in like a wrecking ball” and “never hit habitability so hard” (everything in quotations must be sung in Miley Cyrus’ singing voice). All in all, we all share a laugh and an emotionally charged episode!
