Summary
[edit]DescriptionGemini North Under a Milky Bow (gemini-20140822-milky-bow).tiff |
English: This remarkable photograph shows the Gemini North and Canada-France-Hawai‘i Telescope domes in the pre-dawn twilight. The image, taken during the COLOSSOS Large and Long program program studying the colors of of Solar System objects, shows the Milky Way arching over the domes like a snow-laden trestle. The crescent Moon (the bright object at right) is being caressed by the delicate band of zodiacal light — a belt of dust in the plane of the inner Solar System illuminated by the Sun. Skywatchers can see the zodiacal light only from the darkest sites in the world, attesting to the remarkable clarity of the night sky over Maunakea, where Gemini North is located. If you look carefully, you can see the zodiacal light overlapping the Milky Way and extending ever so delicately above and beyond it. The Milky Way itself carries on to the right of the zodiacal light where it arcs down into the early morning twilight. Gemini North is part of the international community of observatories built to take advantage of the superb atmospheric conditions on this long dormant volcano which rises more than 4,200 meters into the dry, stable air of the North Pacific. The Gemini Observatory’s Hilo Base Facility (HBF) is located in Hilo, Hawai‘i, at the University of Hawai‘i at Hilo’s University Park. |
