The National Science Foundation's Arecibo Observatory in Puerto Rico, known for its studies of asteroids and aliens and for its cameo in a James Bond film, collapsed this morning (Dec. 1). “Arecibo could determine the size, shape and rotation of near-Earth asteroids, and provide much more accurate predictions of their future orbits than can be obtained using optical telescopes alone.” Martha Haynes, the Goldwin Smith Professor of Astronomy (A&S), first used Arecibo in 1973, when she was a summer research intern. The 900-ton platform suspended above the dish fell overnight. Astronomers use Arecibo data especially to study far-off objects such as galaxies, asteroids and pulsars, the rotating neutron stars that emit radio energy in regular waves. The other side of the platform still had cables under tension, he added, so the platform didn't suddenly fall, but took approximately 30 seconds to glide into the radio dish.
