The talk begins at 7 p.m. at the Museum of the Rockies. It is free and open to the public.
Peters will explain some of NASA's big questions, such as how did life begin and evolve, and does life exist elsewhere in the universe? Peters will also explain why Yellowstone National Park is so important to NASA scientists and discuss some of the pioneering research happening in Montana.
The talk is part of the Winter Astronomy Lecture Series sponsored by the Southwest Montana Astronomical Society.
