Dear friends,

Early results from our SETI citizen science platform have come in. Our platform is undergoing the required project review in order to become an official Zooniverse project. As part of this review, beta testers exercise the platform and submit feedback. The response has been impressive, with more than 3,000 image classifications by 100+ volunteers in the first 24 hours. We are experiencing the power of citizen science firsthand and it is a thrill! Ultimately, we hope to collaborate with a large and diverse set of SETI enthusiasts to classify 20,000–100,000 images, identify the most promising technosignature candidates in our data, and generate a labeled training set for our next machine learning application (see Oct. 25, 2021 newsletter to learn how we currently use machine learning in our search). The beta test is expected to last one week, after which we may receive additional feedback from the Zooniverse team. We are eager to incorporate the feedback and launch the citizen science collaboration in early 2023 with our funding partners at NASA and The Planetary Society. UCLA graduate student Megan Li will describe the citizen science platform, science objectives, and anticipated results during her talk at the annual meeting of the American Astronomical Society (AAS) in Seattle, WA on January 12, 2023. I will speak in the same session about our latest search results, including the analysis of our Spring 2022 data.

The debate about Messaging to Extraterrestrial Intelligence (METI) or Active SETI resurfaced briefly with the publication earlier this year of an article titled "A Beacon in the Galaxy: Updated Arecibo Message for Potential FAST and SETI Projects". Active SETI involves deliberately sending a message from Earth in the hopes that it will be received by another civilization. The message proposed in the paper contains 204,000 bits, which is ~120 times longer than the 1974 Arecibo message (see Sept. 7, 2022 newsletter). The topic of Active SETI is controversial in the SETI community. There are several vocal proponents but also many others who urge restraint and encourage broad consultation before sending additional messages. Because other civilizations, if they exist, are almost certainly more advanced than we are, I see little benefit in Active SETI beyond the symbolic value of the 1974 Arecibo message. My thinking is closely aligned with that of the late Frank Drake. In an interview for Science Friday, Frank stated that Active SETI is not necessary and that "our resources are better spent searching." Indeed, there is currently little to gain from transmitting a message to the stars. But imagine what we could learn if we detected a message from an advanced civilization!

I feel extremely grateful to be engaged in the fascinating search for life in the universe and for the privilege of sharing my passion with others like you. Giving Tuesday is around the corner, and if you feel inclined to support our research and teaching mission, please consider making a donation. Your gift will accelerate our search and enable broader participation in SETI.

Happy Thanksgiving and warm regards,

Jean-Luc Margot
