I had a chat yesterday with my neighbor, Paul Gilster (Centauri Dreams), who is an expert on all things outer space, and especially the latest that is known or suspected about the nature of the universe. He was telling me about ‘Oumuamua, the first interstellar object (not from the Solar System) that we have detected passing through the Solar System. It was discovered with the Pan-STARRS telescope, which is the only instrument on Earth that could have seen it. Pan-STARRS first came online only eight years ago.
Our classification of the object has changed as astronomers have learned more about it, ruling out various theories. One of the few speculations that has not been disproven is that ‘Oumuamua is some sort of autonomous space craft, built by a technologically advanced civilization, and sent out to encounter star systems and gather data about their planets and moons, perhaps to be “phoned home.”
Personally, one of my favorite moments in movies is from “The Day the Earth Stood Still” when Klaatu (played by Michael Rennie, not Keanu Reaves) lands his flying saucer on a baseball field in the middle of Washington, DC. Are we ready to meet our neighbors? What’s the etiquette?
This, and other discoveries, have more and more scientists suggesting that we should be making people, our Earth’s inhabitants, ready for the possibility / probability that we may well discover hard evidence of extraterrestrial civilizations in the near future.
