Benjamin was crushed when he learned that 'starquakes' weren't actual ground-shaking events on a star's surface that shook little star buildings and cracked little star roads. Kovi's colleague, astroseismologist Courtney Crawford, explains how asteroseismology is the study of stellar oscillations - rhythmic pulsations in a star’s brightness - that help astronomers understand a star's internal structure, composition and rotation. Courtney wanted to be a butterfly until she watched MythBusters - and that set her down the path to talking to us about starquakes.

We like big shuttles and we cannot lie... Kovi and Benjamin double up their guest payload this episode, as they speak with space historians and authors Emily Carney and Bruce McCandless III. Emily and Bruce just released their new book 'Star Bound' about the evolution of the space program - from the very first person to build a little rocket all the way to astronauts today. They share how their experience brought them together, what inspired their book, and the awesome things we've done - and will soon do - in space.

The absence of evidence is not evidence of absence. Kovi laughed as Benjamin's mind was blown when hearing this knowledge nugget from this week's guest, researcher for the SETI Institute, Dr. Chenoa Tremblay. Who, you asked? Let's put it this way - if there are alien civilizations out there, Chenoa is the person who's going to find it. Seriously. Name a radio telescope - chances are she's used it to look for life, or signs of life, out there in the cosmos. Join us as we discuss biosignatures, technosignatures, and strong opinions on pizza.
