LIGHT POLLUTION
Development Blocked Near Tucson Telescopes

TUCSON, ARIZONA--Astronomers are applauding a decision last week by county officials to reject a $900 million development plan that could have brightened skies and degraded viewing conditions at three major observatories nearby. By a 4-to-1 vote, the Pima County Board of Supervisors turned down a plan to build 6000 homes and a large commercial district on a former ranch at the foot of the telescope-studded Mount Hopkins, 60 kilometers south of Tucson. Instead of savoring their victory, however, scientists have pledged to work harder to preserve dark skies on the outskirts of this rapidly growing southwestern metropolis.
