“If it’s unwanted, it’s harassment,” proclaim signs around the American Astronomical Society’s (AAS) 227th conference, held this week in Kissimmee, Florida. The signs and a Tuesday town-hall meeting entitled “Harassment in the Astronomical Sciences” represent a response to a scandal that rocked the field this past fall. In October, Buzzfeed revealed that famed planet-hunter Geoff Marcy had violated Title IX sexual-harassment policies at the University of California, Berkeley, with the accusations against him spanning nine years.
