Unearth the mysteries of Dark Matter and Dark Energy this weekend at the Los Alamos Nature Center’s planetarium. At 7 p.m., Friday, Aug. 17 Galen Gisler will give a talk called “The Dark Side of the Universe” that will explore these phenomena. The following day, the nature center will show the full-dome film “Phantom of the Universe: The Hunt for Dark Matter” to dive further into this fascinating subject.
Astrophysicists and cosmologists attempt to understand the universe by studying the radiation that comes to us from outer space. Visible, ultraviolet and infrared light; radio waves; x-rays; gamma rays; cosmic rays; neutrinos and gravitational waves all give us clues about the nature, structure and past history of our cosmos. These clues hint at constituents or forces that we cannot directly measure, which we have given the names Dark Matter and Dark Energy.
Galen Gisler will review the evidence for these mysterious entities and discuss research about their nature. Gisler is an astrophysicist who had a 25-year career at Los Alamos National Laboratory. He 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 “Phantom of the Universe: The Hunt for Dark Matter” at 2 p.m., Saturday, Aug. 18. This planetarium show gives an exciting overview of dark matter, starting with the Big Bang to its anticipated discovery at the Large Hadron Collider. Learn more about the fascinating mysteries of dark matter at Friday night’s talk, the film or both!
