NASA launches last "great" telescope
The Earth-trailing orbit will keep the telescope away from the reflected light and heat of the Earth so it can see objects farther away. Potential targets for the device include planet-forming discs around stars, brown dwarves, and galaxies billions of light years away. "The Facility will detect objects that have been too cold, too hidden, or too far away to be seen by other space observatories," says Michael Werner, NASA project scientist.
Workers processed the Space Infrared Telescope Facility in clean rooms. When operational, as in an artist's rendering, it will gather infrared images of the galaxy and beyond.
