Location: Memorial County Park, Loma Mar, CA. The 2025 REU cohort with scientists Dr. Rosalba Bonaccorsi (far left) and Dr. Robert French (second from right).
At the SETI Institute, our mission is "to lead humanity's quest to understand the origins and prevalence of life and intelligence in the universe", and to that end, we invite a select group of undergraduate students to participate in research every summer. During this year's Research Experience for Undergraduates (REU) program, we are proud to welcome twelve aspiring scientists to our office in Mountain View. Each student has a mentor whose research they assist with, getting a breadth of experience in how to read about, conduct, write about, and present scientific findings.
As an extension of the REU program, students participate in several off-site field trips to learn about our environment and discover new ways of viewing the world, life, and intelligence. This summer's cohort recently embarked on a scientist- and chaperone-led trip down the California coast, from Half Moon Bay to Big Sur, where they explored tide pools, pebble beaches, geologic formations, sandy dunes, and redwood forests. Trip leaders asked the students to think about life and intelligence—and how to recognize both—while they explored some of our state's wonderful natural sites.
Astrobiologist Rosalba Bonaccorsi and planetary scientist Robert French led the undergraduates through a series of exercises over the weekend, from observing the animal behavior of local birds and mammals at Pigeon Point to contemplating what it would be like to be aliens arriving on our world and trying to understand what they see at Moss Landing. Several enthusiastic debates were had over the nature of life and intelligence and how an outsider might determine either. How would a silicate lifeform determine life? Are those tiny creatures building structures with thin, nearly invisible strands intelligent? Is there life under the surface of the liquid water? What does it mean when those larger creatures soar through the air in a group?
Overall, the weekend trip was filled with good humor, surprising discussions, and new friendships, all set against the backdrop of lovely weather and fantastic scenery. This past week, the REU students travelled to the Hat Creek Radio Observatory and the Allen Telescope Array for further science and exploration.

Scientists are getting closer in their search for life beyond earth. But with limited federal funding for the search for extraterrestrial intelligence, supporters are the reason cutting-edge scientists can keep their eyes on the sky.
