Where should we look for ET? Avi Loeb, Seth Shostak

Finding intelligence in the cosmos might be done simply by paying attention. While SETI scientists look for radio or optical signals, the astronomy community is perennially on the lookout for all types of cosmic phenomena. One example of the latter is the discovery, three years ago, of what was thought to be a previously unknown asteroid. While asteroids are enormously commonplace in our solar system, this object, christened Oumuamua, is clearly from someone else’s solar system. Harvard astronomer Avi Loeb has suggested that Oumuamua might not be an asteroid at all, but a type of interstellar craft, sent our way by extraterrestrials. Why does he think this, and what is the larger lesson we should heed in our search for alien intelligence? If you like SETI Live, or just like science, support the SETI Institute!
