After tragedy struck the Arecibo Observatory in Puerto Rico on Wednesday, the scientific community mourned the loss of an astronomical landmark.

There is now only one last remaining giant, single-dish, radio telescope in the world: China’s 500-meter Aperture Spherical Radio Telescope (FAST). 

Completed in 2016 and located in the Guizhou province of southwest China, the observatory cost $171 million and took about half a decade to build. Its sheer size allows it to detect faint radio-waves from pulsars and materials in galaxies far away; 300 of its 500-meter diameter can be used at any one time.
