What is dark matter? This elusive “stuff” makes up a quarter of the universe.

Marusa Bradac on Feb. 8 will talk about research on the composition of the universe, properties of dark matter, and the latest discoveries about the universe’s past. Bradac, originally from Slovenia, is a physics professor at UC Davis.

The tools of her trade are telescopes in space, including the Hubble Space Telescope and Spitzer Space Telescope, the future James Webb Space Telescope, and also on the ground, the Keck Telescope in Hawaii.

Registration for this event is required. The program will begin at 6pm, with refreshments and no-host bar from 5:30-6pm at TERC on the campus of Sierra Nevada College in Incline Village.

A $5 suggested donation will be collected at the door.
