The James Webb Space telescope is a space telescope scheduled to be launched this decade. It has been designed to study the first formed galaxies. It would be able to see objects lying up to 1.5×106 km away from the earth. A sun shield will protect the telescope from the heat of the sun. (It is basically meant for maintaining a temperature of about – 225°C required for upkeep of the devices.)
