Hollywood can imagine impressive and convincing alien creatures, but is there any science behind our understanding of what extraterrestrial life might be like? Although we don’t know whether they’ll be green, zoologist Arik Kershenbaum shares his insights into how familiar they might be, using lessons from the behaviors that we see in animals on our own planet.
For thousands of years people have wondered if there are planets like Earth, if they’re common, and if any have signs of life. Sara Seager, a professor of physics and planetary science at MIT who is one of the leading experts on the search for Earth-like planets, shares the latest advances in this revolutionary field. Afterward, Peter Plavchan, a professor of physics and astronomy at George Mason University, brings the skies into your living room with remote control of the GMU Observatory.
