In case you missed it, China has added one more “largest” structure in its collection. The 500-meter Aperture Spherical Telescope or FAST, was completed July last year and was built inside a 45 million year old crater, located in Guizhou province.
FAST holds the distinction of being the largest and most sensitive radio telescope in the world. To put into perspective, imagine joining together 30 football pitches. It’s 140 meters deep and has a 1.6-km circumference. It’s made up of almost 4500 panels.
This $180 million mega-structure has one objective; to search for intelligent life forms in the outer space. Check out the video below to learn more about FAST.
