Herschel ESA's Space Observatory will be located 1.5 million kilometres away from Earth at the second Lagrange point European Space Agency's Herschel Space Observatory (formerly called Far Infrared and Sub-millimetre Telescope or FIRST) launches July 2007. The cryostat technology developed for the ISO mission will enable Herschel to have cooling to within 0.3 degrees of absolute zero. Herschel’s 3.5-metre diameter mirror will collect long-wavelength infrared radiation from some of the coolest and most distant objects in the Universe. The Herschel Space Observatory observe at wavelengths never covered before.
