Herschel
An Infrared and Sub-millimetre Observatory
The Herschel telescope is a scientific space mission developed by the European Space Agency (ESA) dedicated to observing the Universe in the infrared and sub-millimetre ranges (wavelengths between 60 et 670 µm), a window of the electromagnetic spectrum that is still largely unexplored. It measures 9 m in length, 4 m in diameter and will weigh over 3 metric tons upon launch.
