China launches world’s largest radio telescope, 500m in diameterThe instrument would be used to study gravitational waves, stellar radio emissions and potentially signals from extraterrestrial civilizations, Qian Lei, an associate researcher with the National Astronomical Observatories of the Chinese Academy of Sciences, told state broadcaster CCTV.
“In theory, if there is civilization in outer space, the radio signal it sends will be similar to the signal we can receive when a pulsar [spinning neutron star] is approaching us,” Qian said.
FAST is the world's biggest radio telescope with a single dish. The old Soviet RATAN-600 in southern Russia is bigger still, but, unlike China's new telescope, its 576-meter reflector structure resembles a donut. ![[Linked Image from s21.postimg.org]](http://s21.postimg.org/f9dy5y587/Radio_Tel.jpg) ![[Linked Image from s21.postimg.org]](http://s21.postimg.org/6y0fj7y5z/Contact.png) (Contact) RT

I guess the detectors go on wires suspended from the towers around the outside? Moving the detectors around would be the only way I can see to aim the thing.
