New SETI Tool, ‘Technosearch’, Keeps Track of Searches

Technosearch, a new web-based tool that archives all published SETI searches from the 1960s to the present day, has attracted attention since being announced by the SETI Institute in early January. The tool not only allows researchers to quickly access previously hard-to-find work, but also allows users to submit their own searches, ensuring the endeavor will remain current. The tool was developed by Jill Tarter, SETI pioneer and co-founder of the SETI Institute, who said she started the archive as a graduate student. Among those who collaborated to develop Technosearch is former SETI Research Experience for Undergraduates (REU) intern Andrew Garcia. As Garcia pointed out in the statement, “we can’t know where to look for evidence tomorrow if we don’t know where we have already looked”. Technosearch is the first time that all SETI searches and results have been collected in one place and represents a notable boon for the SETI community.

Technological advances in radio astronomy mean that it’s now possible to detect more and more strange and powerful bursts of radio waves, lasting only milliseconds, that intrigue scientists and the general public. Most seem to appear just once, but two have been detected that repeat. The cause of the signals, called fast radio bursts (FRBs) remains unknown – and, as with many strange phenomena, the mysterious nature of FRBs has spurred speculation that their origin may be a sign of extraterrestrial technology. Salon turned to the SETI Institute’s Senior Astronomer, Seth Shostak, for comment:

"It is hard to imagine this type of communication would make much sense to broadcast,” Seth Shostak, a senior astronomer at the Search for Extraterrestrial Intelligence (SETI), told Salon. Moreover, Shostak noted, the FRBs are randomly distributed. "They aren’t coming from one galaxy, they are coming from all over... and when it comes from all over, history tells you it is nature, not aliens.”

While it seems unlikely that the energy bursts are a sign of alien technology, there is a great deal of interest in understanding the perplexing phenomena, as the Huffington Post noted:

Seth Shostak, senior astronomer and director of the Center for SETI Research, a nonprofit based in California that searches for extraterrestrial intelligence, also has high hopes of learning the FRBs’ origin, which he said is “bound to be interesting.”

“These things belch out tens of millions of times as much energy as the sun would belch out in a similar length of time, so whatever it is, it is something very, very powerful,” he told radio station KCBS. “It could be colliding black holes but you don’t expect black holes to collide and then an hour later collide again, and then after that to collide again, right? So, it’s got to be something that can repeat”

In addition to KCBS, Shostak appeared on KGO Radio to discuss the latest detection of a second repeating FRB. As detection methods improve, the interest in closely studying FRBs and unlocking their origins ramps up.

The eVscope telescope was on display at CES in early January, showcasing a new way of stargazing and engaging in citizen science. Touted as one of the most successful crowdfunding projects, Unistellar developed the eVscope in partnership with SETI Institute Senior Planetary Astronomer Franck Marchis. Gadget, a consumer technology magazine, covered the story:

Two years ago, the startup held some of the earliest demonstrations of the eVscope, then in its proof-of-concept phase, at CES… CES is also where Unistellar’s citizen-astronomy ambitions got an enormous boost when the company’s founders met Dr. Franck Marchis, senior astronomer at the SETI Institute. Dr. Marchis has since joined the start-up as Chief Scientific Officer to develop the company’s citizen-science component. Thanks to a partnership between Unistellar and the SETI Institute, the eVscope’s users will be able to join a large community of observers who contribute to scientific discovery while witnessing special astronomical events like comets, supernovae, and asteroids.
