Life, the Universe, and the Search for Extraterrestrial Intelligence (SETI)
Speaker(s): Jill Tarter
Abstract: Hollywood movies about aliens abound, but do they really exist? The real scientific search for evidence of life, and particularly intelligent life, elsewhere in the cosmos is just as exciting as the “reel” version, and a lot more logical. So far, there is ‘life-as-we-know-it’ to guide our speculations and observations. But a new appreciation for the tenacity of life, a growing respect for the world of microbes, and new search technologies involving observatories and spacecraft are rapidly expanding our viewpoint. Many expect surprises. SETI is at the forefront of this research and has plans to extend its range out even further into the galaxy, looking for evidence of someone else’s technology. In the next few decades, scientists will take a much closer look at places within our solar system where liquid water (even vast oceans) may exist and harbor life. They will also probe the closest stars to see if other ‘Earths’ and biospheres exist. Dr. Jill Tarter will describe research in a discipline some call “the archaeology of the future”.
