[[File:The James Webb Space Telescope Face On (29548684133).jpg|thumb|The mirror of the James Webb Space Telescope]]'''James Webb Space Telescope''' is a successor to the [[Hubble Space Telescope]] scheduled for launch in October 2021. The telescope was built by NASA, in cooperation with the Canadian and European space agencies.
The telescope's mirror is 6.5-meters in diameter, compared to Hubble's 2.4-meter mirror. It will observe from the Earth–Sun L<sub>2</sub> Lagrange point, which is 1.5 million kilometers above the Earth. This point is well beyond orbit of the moon, which is 400,000 kilometers from the Earth.
