Astronomy students and faculty celebrated the completion of a new small radio telescope (SRT) on May 1 during a ribbon-cutting ceremony. This is Wesleyan’s first radio telescope, joining three optical telescopes housed at the Van Vleck Observatory on Foss Hill.Radio telescopes are highly complementary to optical telescopes. Able to see through cloud cover, they are not limited by weather. Also, in a “radio sky,” the remnants of exploding stars and distant supermassive black holes shine brightly.This fall, the SRT will allow Wesleyan students and faculty to detect remote radio sources, map galactic rotation and conduct other kinds of astronomical research. It will be an essential tool in the university’s astronomy courses.The SRT has a motorized arm that can position the dish to face any part of the sky. Quasars, pulsars, and the afterglow of the Big Bang have all been discoveries of radio astronomy.Students enrolled in Assistant Professor Meredith Hughes’ Radio Astronomy Class created the functional radio telescope in one semester. They followed design specifications for a small radio telescope developed by Alan Rogers at MIT’s Haystack Observatory. Wesleyan is the first university to assemble a SRT from upgraded system plans published by Haystack.Hughes, pictured directing the satellite through a computer, divided her class into three teams. Each team was responsible for acquiring and assembling the components for different sections of the telescope.Of the 10 astronomers who have received Nobel prizes in astronomy, six used radio telescopes in their research.Classmates, with the help of Astronomy Department faculty, used the new device to detect the sun during a “First Light” celebration.
