China has fitted the final piece on what will be the world’s largest radio telescope.
The 500m-wide Aperture Spherical Telescope, or FAST, is the size of 30 football fields.
The $250 million (NZD) satellite project will be used to explore space.
Advancing China’s space program remains a key priority for Beijing.
FAST will replace the Arecibo Observatory in Puerto Rico, which is around 300m wide, as the world’s largest telescope.
Scientists are now due to start trials of the telescope, which took about five years to build. It isn’t due to fully begin operations until September.
