Lowell Observatory The Lowell Observatory near downtown Flagstaff, Ariz., is one of the oldest of its kind in the nation. The Alvan Clark 24-inch refracting telescope is so powerful that it was used at the turn of the century to look for life on Mars. The public viewing program runs from June through August, 5:30 p.m. to 10 p.m. Monday through Saturday. Fees: $6 for adults and $3 for youngsters. For more details, call (928) 774-3358 or go to the website. Pluto Dome is part of the Lowell Observatory. Pluto was discovered there in 1930.
