In the last decade, we have devised amazing instruments to glare unflinchingly at the stars and discovered that other planets are common around them. These exoplanet discoveries have thrown gasoline on the fire of the astrobiology field, where scientists seek to explore whether life might exist beyond Earth. But they have also fueled SETI, or the search for extraterrestrial intelligence. If life does evolve on other worlds, then we may very well find more than just biosignatures like oxygen.
We might find technosignatures, too. These are things like radio signals, or even megastructures; that is, artificial objects on a gigantic scale such as hypothesized star-sized supercomputers. Now, Supercluster reported in an article this week, NASA has quietly begun to fund the search for such alien megastructures for the first time in the agency’s history…
The best news [to me] is that we’re moving well beyond the typical American cultural response to a new critical investigation of unusual phenomena. Breaking out of the historic mold of latching onto singular means of investigation – in expectation of an equally singular answer to the question, “What’s out there?”
RTFA for early days projections, the first rounds of investigative style.
