Weekly Space Hangout — December 7, 2022: The Science of the L1527 "Butterfly" with Dr. Karl Stapelfeldt

During our November 16th show, Carolyn Collins Petersen introduced us to the hourglass/butterfly of L1527, an image captured by JWST using its onboard NIRCam. (You can read the original story here. This week we are joined by Dr. Karl Stapelfeldt, Chief Scientist for NASA's Exoplanet Exploration Program at JPL who will help us understand the science behind this amazing structure.

Karl earned a B.S.E. in Aerospace Engineering and Engineering Physics at Princeton University, and a Ph.D. in Astrophysics at Caltech. His career at NASA includes positions at both the Jet Propulsion Laboratory and most recently at the Goddard Space Flight Center, where he has served as the Chief of Goddard's Exoplanets and Stellar Astrophysics Laboratory since 2011.

Karl's NASA science contributions include project science roles for the Hubble and Spitzer Space Telescopes and science observations using the Herschel Space Observatory. He served as chair of the Exoplanet-Coronagraph Probe-Scale Science and Technology Definition Team, and as a member of the Astrophysics Subcommittee of the NASA Advisory Council.
