Join us on June 28 at 2:30 PM PT for the next episode of SETI Live, hosted by Dr. Lauren Sgro, featuring special guest Dr. Adam C. Schneider (United States Naval Observatory).

What happens when hundreds of thousands of volunteers team up with NASA to explore the sky? In the case of Backyard Worlds: Planet 9, thousands of new brown dwarfs.

NASA citizen scientists have helped discover more than 3,000 brown dwarfs, effectively doubling the known population of these mysterious objects over the past decade. These discoveries are helping astronomers better understand the boundary between planets and stars, revealing rare ultra-cool worlds, extreme T subdwarfs, and even brown dwarfs that may host aurorae.

Lauren and Adam will discuss how citizen scientists made these discoveries, why brown dwarfs are so difficult to detect, and what this growing catalog is teaching us about our galactic neighborhood.

Bring your questions for the live Q&A.

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.
