The Massive Telescope Built Into Nature

China’s massive radio telescope is not sitting on top of the ground but is built directly into a giant natural sinkhole. This allows its record-breaking 500-meter dish to remain stable while scanning deep space.

The bowl-shaped depression in Guizhou acts as the perfect cradle for this colossal scientific instrument. By using the natural landscape, engineers avoided the impossible task of building a flat support structure for such a massive dish. This unique location also shields the telescope from radio interference coming from the horizon. It remains the most sensitive ear we have for listening to the whispers of the distant universe.
