👏The world's largest single-dish radio telescope — China's FAST — has undergone a major upgrade. The project will deploy dozens of medium-sized antennas around FAST, forming a giant integrated aperture array with FAST at its core. This innovative design effectively overcomes the inherent spatial resolution limitations of single-dish telescopes, while significantly enhancing overall observational sensitivity. #ChinaTravel #ChinaTech #Guizhou #telescope #FAST #upgrade Guizhou, China Live in Guizh

The deployment of NASA’s James Webb Space Telescope’s solar array will be its first, and most important. Small but efficient, the 5900mm (19.36ft) long solar array will release itself like an accordion to a straightened configuration shortly after launch. Its purpose is to convert sunlight into electricity to operate the telescope’s propulsion and communication subsystems, as well as its scientific instruments. Webb is the largest, most complex, and the first folding space telescope ever attempt
