The European Space Agency's Herschel Space Observatory has the largest single mirror ever built for a space telescope. The 3.5-metres diameter mirror will collect long-wavelength radiation from some of the coldest and most distant objects in the Universe. In addition, Herschel will be the only space observatory to cover a spectral range from the far infrared to sub-millimetre. ESA's Herschel mission has been designed to unveil a face of the early Universe that has remained hidden until now.

Herschel will be able to observe dust obscured and cold objects that are invisible to other telescopes. Its major objective will be discovering how the first galaxies formed and how they evolved to give rise to present day galaxies like our own. Additional targets for Herschel will include clouds of gas and dust where new stars are being born, disks out of which planets may form and cometary atmospheres packed with complex organic molecules. Herschel was launched on an Ariane 5 ECA rocket, together with ESA's Planck spacecraft, on 14 May 2009.
