The European Space Agency's Herschel Space Observatory (formerly called Far Infrared and Sub-millimetre Telescope or FIRST) has the largest single mirror ever built for a space telescope. At 3.5-metres in diameter the 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. --- Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com --- HERSCHEL MISSION: The Herschel Space Observatory is the largest infrared space observatory launched to date. Equipped with a 3.5 metre diameter reflecting telescope and instruments cooled to close to absolute zero, Herschel will observe at wavelengths that have never previously been explored. After a roughly 60-day journey from Earth, Herschel will spend a nominal mission lifetime of three years in orbit around the second Lagrange point of the Sun-Earth system (L2). Infrared astronomy is a young and exciting science. In recent decades infrared astronomers have unveiled tens of thousands of new galaxies, and have made surprising discoveries such as the huge amounts of water vapour that fill our Galaxy. Yet scientists know there is still much more to discover. Objects such as other planetary systems, or ...
