ASTR 207 - Extraterrestrial Life in the Galaxy: A Sure Thing, or a Snowball's Chance?

Institution:

Williams College

Subject:

Astronomy

Description:

A focused investigation of the possibility of life arising elsewhere in our Galaxy, and the chances of our detecting it. In this course, pairs of students will explore the astronomical and biochemical requirements for the development of Earth-like life. We will consider the conditions on other planets within our solar system as well as on newly-discovered planets circling other stars. We will also analyze the famous "Drake Equation," which calculates the expected number of extraterrestrial civilizations, and attempt to evaluate its components. Finally, we will examine current efforts to detect signals from intelligent alien civilizations and contemplate humanity's reactions to a positive detection.
