PEEC News:

Unearth the mysteries of Dark Matter and Dark Energy this weekend at the Los Alamos Nature Center’s planetarium.

Astrophysicist Galen Gisler will give a talk called “The Dark Side of the Universe” at 7 p.m. Friday that will explore these phenomena. The following day, the nature center will show the full-dome film “Dark Matter Mystery” to dive further into this fascinating subject.

Astrophysicists and cosmologists attempt to understand the universe by studying the radiation that comes from outer space. Visible, ultraviolet and infrared light; radio waves; x-rays; gamma rays; cosmic rays; neutrinos and gravitational waves all give clues about the nature, structure and past history of the cosmos. These clues hint at constituents or forces that cannot be directly measured, and which have been given the names Dark Matter and Dark Energy.

Gisler will review the evidence for these mysterious entities and discuss research about their nature. He had a 25-year career at Los Alamos National Laboratory and has been involved in a variety of activities at the Lab, including particle beams, extragalactic jets, plasmas, astronomical transients and more. Although semi-retired, he works as an Associate at LANL on ways of defending the Earth against asteroid impacts.

The nature center is showing the full-dome film “Dark Matter Mystery” at 2 p.m. Saturday, Feb. 9. This planetarium film explores the evidence for dark matter and the experiments currently being conducted to try to detect dark matter and what it might be composed of. Learn more about the fascinating mysteries of dark matter at Friday night’s talk, the film or both.
