mccullough and his team employed a relatively inexpensive telescope called an xo telescope, made from commercial equipment, to search for extrasolar planets. this telescope consists of two 200-millimeter telephoto camera lenses, and resembles binoculars in shape. it stands on the summit of the haleakalā volcano in hawaii. their first discovery of a jupiter-sized planet orbiting a sun-like star 600 light-years from earth in the constellation corona borealis—xo-1b—was reported may 16, 2006 on newswise.
