The legendary radio telescope at Arecibo Observatory in Puerto Rico collapsed on Dec. 1, sending shock waves throughout the astronomy and astrophysics communities. The telescope, the world s most powerful radar that was used by scientists for almost six decades to send beams to and receive signals from outer space to elucidate the ways of the universe, also is cemented in the history of the U.S. Department of Energy s Princeton Plasma Physics Laboratory (PPPL).
It was at Arecibo in 1974 that Russell Hulse, a University of Massachusetts graduate student, along with his advisor, James Taylor, discovered the first binary pulsar - a pulsar comprised of two stars in very close proximity that rotate around each other. Hulse was a physicist at PPPL from 1977 to 2007 and Taylor became a Princeton physicist. Th
