외계와의 소통 시도했던 거대 전파망원경, 57년 만에 결국 붕괴

The world's second biggest telescope in Puerto Rico has collapsed,... following gradual deterioration in recent months.
The 57-year old Arecibo Telescope was installed and managed by the U.S.
Over the years the giant bowl-shaped reflector had been used by scientists for various studies,... including finding potentially dangerous asteroids and looking for signs of extra-terrestrial life.
In August, cables supporting the reflector broke, forcing officials to close the observatory.
They say repairs would cause more damage than leaving it to be demolished.
