In August, a detached auxiliary cable tore through the dish of Arecibo Observatory. Last week, another cable failed.

The already battered Arecibo Observatory was hit with another blow on 7 November when one of its 12 main support cables snapped and tore through the radio telescope’s main dish. The incident comes just 3 months after the failure of another cable. Researchers are concerned that increasing stresses on remaining cables could lead to cascading failures and the collapse of the antenna platform that is suspended over the dish.
