Located in China’s south-western region, the world’s largest radio telescope might be the next best chance Earth has at locating alien life.

The radio telescope was built in a natural basin in the Guizhou Province’s Pingtang County and spans 500 metres in diameter. The telescope was aptly named the Five-hundred-meter Aperture Spherical Telescope. Or FAST, for short. What makes FAST special (apart from its staggering size), is its active surface that adjusts to researchers’ desired sky direction. This telescope can cover the sky for 40 degrees from its zenith. This is double the range of the Arecibo Observatory in Puerto Rico.

Pictured above is an overhead shot of FAST, taken on 26 November 2015. The project will reportedly be completed in September of this year.
