The James Webb Telescope

The James Webb Space Telescope will be a major advance over all previous infrared observatories. Its primary mirror will be 50 times the area of the Spitzer Space Telescope, and its infrared images will have eight times the resolution (about the same resolution in the near-infrared as the Hubble has in the visible spectrum). This will allow the device to capture images of the structure of the first galaxies in the Universe with unprecedented detail. The wavelengths that the Webb will image can not be seen at all from the surface of the Earth because of our atmosphere.
