James Webb Space Telescope (Paperback)

High Quality Content by WIKIPEDIA articles The James Webb Space Telescope (JWST), previously known as Next Generation Space Telescope (NGST), is a planned next-generation space telescope, optimized for observations in the infrared. The main technical features are a large and very cold 6.5 meter diameter mirror, an observing position far from Earth, orbiting the Earth-Sun L2 point, and four specialized instruments. The combination of these features will give JWST unprecedented resolution and sensitivity from long-wavelength visible to the mid-infrared, enabling its two main scientific goals - studying the birth and evolution of galaxies, and the formation of stars and planets.
