Do you know which is the most powerful telescope that was launched into space by NASA? It's the US space agency's James Webb Space Telescope (JWST). This specialised telescope is capable of seeing infrared light that is not visible to the human eye, enabling it to see early stars and galaxies that are millions - or even billions - of years old. Find out how the JWST works on the latest episode of Gadgets 360 with Technical Guruji and learn how it is helping astronomers and scientists decode the history of the universe.
