A3. Intelligent Life in the Universe

Are we alone in the universe?  Science is closing in on solid answers about life beyond earth, and, eventually, on locating beings with the technology and interest to communicate with us.  Recent NASA research shows that many of the stars in our galaxy have orbiting planets, including some similar to our own earth. Space programs worldwide are studying other solar-system planets, seeking signs of living organisms, past or present.  “Extra-terrestrial intelligence” programs are seeking signals coming from technically-developed civilizations; we are sending out messages to announcing our presence to the universe at large, hoping that communications might someday be established.  No math is required, no prior science background is necessary.  Just bring along a healthy curiosity!

INSTRUCTOR: Les Blatt is Professor Emeritus of Physics and Education at Clark University.
