Why you should listen
Dr. Carrie Nugent is an asteroid hunter who works with a small team to discover and study asteroids at Caltech/IPAC. She earned her PhD in Geophysics and Space Physics from UCLA in 2013 and is a 2016 TED Fellow. Specializing in thermophysical modeling, Nugent uses observations from the space-based infrared telescope NEOWISE to better understand asteroid surfaces. Asteroid 8801 Nugent was named in her honor.
In her free time, Nugent hosts and produces Spacepod. On this weekly podcast, she invites astronomers, planetary scientists and engineers to sit, share a drink and tell the world about their corner of the cosmos.
Nugent is the author of the TED Book, Asteroid Hunters.
