Ben Montet
Host Paul Carr talks to astronomer Ben Montet,who has, with his colleague Joshua Simon, just published the result that Tabby's Star (KIC 8462852) dimmed considerably over the four year course of the Kepler Space Telescope prime mission.

Guest Bio:

Ben Montet recently defended his Ph.D. at the California Institute of Technology, where his thesis work focused on understanding the properties of low-mass stars and their companions. During his thesis, he led teams which measured the occurrence rate of Jupiter-sized planets in wide orbits around low-mass stars, developed the first catalog of confirmed transiting planets from the K2 mission, and characterized the first non-inflated brown dwarf with a directly measured mass, radius, and atmospheric properties. In September, he will begin a Carl Sagan Fellowship at the University of Chicago.

Burst 18 - Nick Nielsen on the Spoor of Civilizations

Released: 4 July 2016
Duration: 20 minutes, 41 seconds

SETI research is much like the traditional task of a tracker, who seeks the spoor of elusive quarry through a wilderness. In the search for life, intelligence, and exocivilizations we find ourselves in the position of seeking the spoor of these higher emergent complexities in the cosmological wilderness.
