The James Webb Space Telescope
Today’s Video of the Day from NASA Goddard introduces the James Webb Space Telescope, which will be the largest and most powerful telescope ever sent into space.
Named after NASA’s second administrator, the massive telescope is three stories high and the size of a tennis court. The instrument is so large that it will have to be folded to fit into the rocket that will carry it to space after being launched in French Guiana.
The telescope has been designed to observe infrared light with such extraordinary sensitivity that it will be able to see the first galaxies born after the Big Bang over 13.5 billion years ago.
The international Webb mission was funded in part by the European Space Agency and the Canadian Space Agency. Scientists all over the world will have access to the Webb telescope, which is 100 times more powerful than the Hubble Space Telescope.
