Get ready for a new kind of light show after NASA’s James Webb Space Telescope launches in late 2018. The supersensitive device will fly to a spot a million miles from Earth and then orbit the sun. It will come with infrared eyes and a special shade to protect it from the sun’s glare. They will allow the telescope to gather infrared light, which is invisible to human eyes, and probe the formation of the first galaxies, among many other things.
