RIVERSIDE, Calif. (www.ucr.edu) — The University of California, Riverside Science Lecture series continues Jan.12 with a talk about how UC Riverside scientists are using their latest discoveries about the evolution of the early Earth to guide NASA’s search for life elsewhere in the universe.

Tim Lyons, a distinguished professor of biogeochemistry at UC Riverside and the director of the university’s Alternative Earths Astrobiology Center, will give the talk called “Alternative Earths: How Earth’s Past Guides NASA’s Search for Life.”

The event, which is scheduled from 6 p.m. to 7:30 p.m. on campus at the University Theatre (Humanities 400), is free and open to the public. There is free parking in parking lot 6. There will also be a raffle for a limited edition lecture series poster.

After the lecture, there will be refreshments and telescope viewing outside the theater hosted by volunteers from the Riverside Astronomical Society and the UC Riverside astronomy division. Guests can view the full moon, Mars, the Orion Nebula, and the Double Cluster, among other celestial neighbors.

After the talk by Lyons, there will be three more lectures as part of the “Are We Alone?” lecture series, which is sponsored by UC Riverside’s College of Natural and Agricultural Sciences:

  • Wednesday, February 1. “Ocean Worlds: Missions to Icy Moons and Dwarf Planets.” Speaker: Kevin Hand, deputy project scientist, solar system exploration directorate, NASA Jet Propulsion Laboratory.
  • Thursday, March 23. “Mars 2020 & Beyond: Will We Find Life on the Red Planet?” Speaker: Ken Williford, deputy project scientist, Mars 2020 Mission and director, Astrobiogeochemistry Laboratory, NASA Jet Propulsion Laboratory.
  • Thursday, April 13. “Alien Planets: Are Other Earths Lurking in Our Galaxy?” Speaker: Antigona Segura Peralta, professor of astrobiology, National Autonomous University of Mexico.
