Many of us have dreamed of what alien life may be like. We've created extraterrestrial beings in our science fiction stories, and we've imagined what a visit to an alien biosphere might be like. With upcoming missions to other worlds in our solar system and continued discoveries about planets that orbit other stars far away, it begins to feel like we are continually approaching a time when we might have an answer to the age-old question, "Are we alone in the universe?" What might alien life be like if it exists? Astrobiologists have a lot of ideas, mostly based on what we know about life here on Earth. In the Craziest Creatures on Earth, we'll learn about some of the weird creatures that dwell on this planet and what the extremes of life on Earth can teach us about life in general. What are the limits of life? Should we expect aliens to fly, or walk, or swim? Will aliens have senses of sight and hearing that are similar to ours? Join Dr. Graham Lau and Fiske Planetarium for a presentation and discussion about the world's wackiest organisms and what they can tell us about potential alien life.
