Professor Katelyn Allers talks about how you can discover small cold stars! She is a member of the Backyard Worlds project, which is a collaboration between astronomers and citizen scientists. This project searches for brown dwarfs, which are some of the closest objects to our solar system.
Brent Barbee returns to the show to talk about deflecting asteroids. He explains how an asteroid might react to an impact, and also talks about the proposed DART mission, which would change the orbit of a small asteroid moon.
