NORMAN — A University of Oklahoma associate professor is scheduled to shine light on dark matter that’s prevalent throughout the universe.

Yun Wang, a cosmologist and associate professor of physics and astronomy, will speak at 7 p.m. today at Sam Noble Oklahoma Museum of Natural History.

Her free, public presentation on dark matter, estimated to account for 90 percent of matter in the universe, will conclude OU’s monthly International Year of Astronomy lecture series.

A stargazing session with telescopes provided on the museum grounds will follow the lecture, weather permitting, and a pair of binoculars will be given away before Wang speaks.

"The expansion of the universe is accelerating today, apparently driven by some form of unknown energy, or ‘dark energy,’” Wang explained.

"I will discuss the observational evidence for dark matter and dark energy, the techniques for probing their nature and future prospects for solving these cosmic mysteries,” she said.
