Arizona cultural activity - Kitt Peak National Observatory and Tucson's streetlights  2007-12-20


Another Tucson highlight - about 35 miles west of Tucson in the desert mountains is the Kitt Peak National Observatory, since the relatively clean desert air in the Tucson area has made this area popular for astronomical research.    We were able to visit there at sunset and into the evening during a public session.



  To reduce light pollution in the area, even the streetlights within the city of Tucson are made with flat lenses that point completely downwards.   You'll note that around here the streetlights emit light from the sides




Seen at Kitt Peak:  "The Pleiades, also known as M45, the Seven Sisters, Subaru (in Japan), are an open cluster in the constellation of Taurus. It is among the nearest to the Earth of all open clusters".    And if you ever wondered about the stars on a Subaru, now you know.   However the logo seems to have only 6 stars.
