Explanation
The James Webb Space Telescope (JWST), launched on 25 December 2021, is positioned at the Sun-Earth Lagrange point L2, approximately 1.5 million km (15 lakh km) from Earth on the side opposite the Sun. From this position it effectively orbits the Sun in synchrony with the Earth, which gives it a stable thermal environment and an unobstructed view of deep space.
