Chinese technology gurus have finished work on the world's largest radio telescope, which will hunt for extra-terrestrial life and explore space.
The final piece of 4,450 panels was fitted into the centre of the 500m-wide Aperture Spherical Telescope, or FAST, over the weekend.
The telescope, which cost $180 million took five years to build and is scheduled to be switched on from September.
"The project has the potential to search for more strange objects to better understand the origin of the universe and boost the global hunt for extra-terrestrial life," Zheng Xiaonian, deputy head of the National Astronomical Observation under the Chinese Academy Sciences, which built the telescope, told Xhinua news agency.
The 9,000 people that live within a 5 km radius of the centre will be relocated to ensure radio silence in the area.
After September, the telescope will be made available to researchers across the world, and will help detecting pulsars and gravitational waves. FAST is expected to eventually be able to detect amino acids, the building blocks of proteins, which would signal life on other planets.
