Although the Hubble Space Telescope was upgraded just 2 months ago, astronomers are already hard at work on its successor. Dubbed the Next Generation Space Telescope, this device would feature a primary mirror two to three times the diameter of Hubble's and might record some of the earliest flickers of starlight in the cosmos. A large sun shield would keep the telescope cold enough to make observations in the infrared. (Illustration: Ball Aerospace) More...
