    The world’s largest radio telescope was finished in China.

FAST is a five-hundred-metre telescope. It is also called Tian-yan (“The Eye of Heaven”), with a dish the size of 30 football grounds, deep in the mountains of south-west China’s Guizhou Province. The giant dish is built on a bowl-like valley.

The surrounding area has “radio silence” as there are no towns and cities within a 5-kilometre radius(半径范围）and only one county centre within 25 kilometres.

FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will e able to pick up weaker signals.

The radio telescope is like an ear, listening to meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(银河系)and explore the origins of the universe. “Any of its discoveries will lead to a Nobel Prize,” said Joseph Taylor, a Nobel Prize winner.

The telescope is expected to remain the global leader for the next 10 to 20 years.
