Understand the universe

“Modern Cosmology” will be the topic at ‘Imiloa Astronomy Center’s next Maunakea Skies program at 7 p.m. Friday, Feb. 15.

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

Over the past century, advances in astronomy and physics have brought scientists a detailed picture of the structure and evolution of the universe. Despite this success, however, the composition of the overwhelming majority of the contents of the universe remains a mystery.

Radford will outline the development of modern cosmology and describe the current understanding of the 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.

The non-member rate is $10. Pre-purchase tickets at the ‘Imiloa front desk or by phone at 969-9703.

‘Imiloa Astronomy Center of Hawaii is located at 600 ‘Imiloa Place in Hilo, off Komohana and Nowelo streets at the University of Hawaii at Hilo Science and Technology Park. For more information, go to www.imiloahawaii.org, or call 969-9703.

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 andinstrumentation.

The program will be hosted by Shawn Laatsch, ‘Imiloa’s planetarium manager. 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.
