Dr. Simon Radford of the Caltech Submillimeter Observatory will present an in-depth look at the composition of the universe.

“Modern Cosmology” is the topic at ‘Imiloa Astronomy Center’s next “Mauna Kea Skies” program at 7 p.m. Friday, Feb. 21.

Over the past century, advances in astronomy and physics have created a detailed picture of the structure and evolution of the universe.

Despite this success, the composition of the overwhelming majority of the content of the universe remains a mystery.

Radford will outline the development of modern cosmology and describe our current understanding of the overall properties of the universe. He will emphasize how observations at radio and submillimeter wavelengths, in particular observations of the cosmic microwave background radiation, complement other evidence to develop a complete picture of the universe.

Radford is the technical manager of the Caltech Submillimeter Observatory on Mauna Kea. He received his doctorate in astronomy from the University of Washington in Seattle based on observations of the cosmic background radiation. Since then, he has worked at the Institute for Radio Astronomy in the Millimeter in Grenoble, France, and at the National Radio Astronomy Observatory in Tucson, Ariz.

Since 2004, he has been a member of the professional staff of the California Institute of Technology. His research has included observations of the CBR, studies of the interstellar medium in distant ultra luminous galaxies, characterization of observing conditions at telescope sites, and development of telescopes and instrumentation.

The “Mauna Ka Skies” program will be hosted by Chris Phillips, ‘Imiloa planetarium staff. He will provide observational highlights of the current night sky over Hawaii, pointing out prominent constellations and stars one can see during this time of year.

The monthly planetarium presentations are held on the third Friday of each month. Cost is $8 for Individual, Dual, Kupuna and Family Members; $6 for Patron Members; Free for Silver, Gold and Corporate Members. Non-member rate is $10. Pre-purchase tickets at the ‘Imiloa front desk or by phone at 969-9703.
