Planets, Life, and the Universe Lectures and Events

The Planets, Life, and the Universe lecture series brings high-profile speakers to the JHU/STScI campus to discuss current topics of interest in astrobiology and draws a large and steadily increasing audience. It is supported by the NASA Astrobiology Institute, the Space Telescope Science Institute, the Department of Biology and the Department of Physics and Astronomy of Johns Hopkins University, and the Ernst Cloos Memorial Fund.

Planets, Life, and the Universe Lecture Series presentations are also webcast live. Webcasts can be viewed at the STScI webcast site during the scheduled presentation, and can be found afterward in the STScI webcast archive.

Organizing committee: Jocelyne DiRuggiero (chair), Maya Gomes, Sarah Horst, Peter McCullough, David Sing, Sabine Stanley, and Kevin Stevenson
