John Simkin Posted October 17, 2004 Share Posted October 17, 2004 The Spitzer Space Telescope (formerly SIRTF, the Space Infrared Telescope Facility) was launched into space by a Delta rocket from Cape Canaveral, Florida on 25 August 2003. During its mission, Spitzer will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space between wavelengths of 3 and 180 microns (1 micron is one-millionth of a meter). Most of this infrared radiation is blocked by the Earth's atmosphere and cannot be observed from the ground. Its highly sensitive instruments give us a unique view of the Universe and allow us to peer into regions of space which are hidden from optical telescopes. Spitzer is the largest infrared telescope ever launched into space and this website provides the latest news and photographs from its travels. http://www.spitzer.caltech.edu/ Link to comment Share on other sites More sharing options...
