Arecibo telescope collapses, ending 57-year run

The Areci­bo Obser­va­to­ry is gone. Its 900-ton instru­ment plat­form, sus­pend­ed above a dish in the karst hills of Puer­to Rico, col­lapsed this morn­ing, at about 8 a.m. local time, says Ramon Lugo, direc­tor of the Flori­da Space Insti­tute at the Uni­ver­si­ty of Cen­tral Flori­da, which man­ages the 57-year-old radio tele­scope for the Nation­al Sci­ence Foun­da­tion (NSF).
