A big Radar created by China called FAST which can detect alien behaviour

The biggest Radar in the world ready to catch alien signals.

Recently, Science developed rapidly. As evidence, there is a big Radar created by China called FAST (Five hundred metre Aperture Spherical Telescope) the radar located in remote area around mountains of Guizhou, China. This area was protected by technology which was can block cell phone signal or wifi, because signals can be causing trouble on the Radar system. The radar build in early 1960S with size of dish 500 metres, and across is about 200 metres. The function of Radar claim that it can detect alien behaviour by dish and telescope can focuses in other object, while the mirror panels receiver can move in conjunction. They have moving flexible to find out object in the sky.
