Long an underfunded, fringe field of science, the search for extraterrestrial intelligence may be ready to go mainstream.
Astronomer Jason Wright is determined to see that happen. At a meeting in Seattle of the American Astronomical Society in January, Wright convened “a little ragtag group in a tiny room” to plot a course for putting the scientific field, known as SETI, on NASA’s agenda.
The group is writing a series of papers arguing that scientists should be searching the universe for “technosignatures” — any sign of alien technology, from radio signals to waste heat. The hope is that those papers will go into a report to Congress at the end of 2020 detailing the astronomical community’s priorities. That report, Astro 2020: Decadal Survey on Astronomy and Astrophysics, will determine which telescopes fly and which studies receive federal funding through the next decade.
“The stakes are high,” says Wright, of Penn State University. “If the decadal survey says, ‘SETI is a national science priority, and NSF and NASA need to fund it,’ they will do it.”
