Description
space telescope
James Webb telescope is larges, the most advance, and the most expensive space telescope ever built. It is possible to track the position of JWST on NASA website.
The telescope originally known as the Next Generation Space Telescope, was renamed after James E. Webb, who was the administrator of NASA from 1961 to 1968.
Expectations are high, so we are expecting even more new discoveries than from the Hubble Space Telescope.
