Exploring the Universe with Dr. Norio Kaifu

Written by Gayle Olson

During 1998 we were fortunate to attend a dinner hosted byrepparttar Japanese Chamber of Commerce and Industry of Hawaii, featuring a lecture by Dr. Norio Kaifu. Professor Kaifu isrepparttar 127718 director ofrepparttar 127719 Subaru Telescope, National Astronomical Observatory of Japan (NAOJ) and has heldrepparttar 127720 position as vice president ofrepparttar 127721 International Astronomical Union (IAU) since 1997. A specialist in radio astronomy, infrared astronomy and interstellar matter, Dr. Kaifu has published some 100 papers on astronomy in addition to 15 popular science books. Before joiningrepparttar 127722 Subaru in 1990, he was a director, a professor and an associate professor atrepparttar 127723 Nobeyama Radio Observatory, and a senior research associate inrepparttar 127724 Faculty of Science atrepparttar 127725 University of Tokyo. As an amateur backyard astronomer we were delighted to learn ofrepparttar 127726 possibilities this new telescope will bring torepparttar 127727 exploration of universal knowledge.

Dr. Kaifu shared his views aboutrepparttar 127728 design ofrepparttar 127729 new telescope, cylindrical in shape, rather than dome, it can be more optimal for wind resistance. The 8-meter diameter glass mirror is only 8 inches thick and has taken six years to construct and polish. The mirror is controlled by two Fujitsu parallel computers, withrepparttar 127730 largest memory capacity inrepparttar 127731 world with 261 supporting structures. 100 times per secondrepparttar 127732 computer adjustsrepparttar 127733 mirror to counteractrepparttar 127734 atmospheric turbulence, which we see as twinkling stars. The mirror can be controlled byrepparttar 127735 computer by each second, to obtainrepparttar 127736 best view ofrepparttar 127737 deeper universe. Mauna Kea was chosen as a location forrepparttar 127738 new Japanese telescope because ofrepparttar 127739 stable weather and easy access.

The winds ofrepparttar 127720 hurricane spin in a counterclockwise direction inrepparttar 127721 Northern Hemisphere and clockwise inrepparttar 127722 Southern Hemisphere.

Inrepparttar 127723 North Atlantic hurricane season is from June 1 to November 30. Overrepparttar 127724 Western Pacific,repparttar 127725 typical cyclone season is never quite over.
