On Sunday, officials cut the ribbon on the FAST (Five-hundred-metre Aperture Spherical Telescope), located in a basin in the mountainous Pingtang County in Guizhou, southwest China.

These types of telescopes are meant to detect radio emissions from the sky, and could help detect faraway messages from space.

A researcher with the Chinese Academy of Sciences said that the FAST has already detected electromagnetic waves coming from a pulsar about 1,351 light-years away, Xinhuareported.

Officials also noted that the huge structure represents a leap forward in space research for China, where it has traditionally lagged behind Western powers such as the U.S. and Germany.

Researchers worked on the FAST for 17 years before construction began, the official state paper said.

Earlier this year, in constructing the telescope, the government forcibly uprooted over 9,000 residents within a 5km radius, to make way for the massive structure.
