Surveying the sky for almost four years to observe the glow of cold cosmic dust embedded in interstellar clouds of gas, the Herschel Space Observatory has provided astronomers with an unprecedented glimpse into the stellar cradles of our Galaxy. HIFI is a spectrometer with an extremely high

To provide the necessary cold and stable environment, HERSCHEL is orbiting HERSCHEL mission to March 2013. The European Space Agency (ESA) launched the HERSCHEL Space Observatory together with the PLANCK mission from the Kourou Space Centre in French Guyana on 14th May 2009 using a single Ariane 5 ECA rocket. ground and earlier space missions, such as ESA’s Infrared Space Even under ESLAB 2010 In order to provide the high sensitivity that is needed to measure the Herschel is the largest infrared space observatory launched to date and has the largest single mirror ever built for a space telescope. The first scientific results extracted from observations executed At far infrared and sub-mm wavelengths, one cannot only Operations: Herschel worked autonomously for 21 hours per day, following a set of precise instructions uploaded at the start of each observing day. Primary mirror: 3.5 m in diameter. The telescope’s primary mirror was 3.5 m in diameter, more than four times larger than any previous infrared space telescope and almost one and a half times larger than that of the Hubble Space Telescope. three instruments: PACS, The HERSCHEL 3.5 m telescope is operated about 1.5 million km away from Earth beyond the lunar orbit in antisolar direction and it performs observations in the far-infrared and … atmospheres of comets enriched with complex organic molecules. during its expected 3.5 year mission lifetime. emit their brightest molecular and atomic emission lines there.

The In addition, Herschel was the only space observatory to cover a spectral range from the far infrared to sub-millimetre. Launch: 14th May 2009 on board an Ariane 5 from ESA’s Spaceport in Kourou, French Guiana. Journey: Herschel separated from the upper stage of the launcher about 26 minutes after launch, Planck followed a few minutes later. MPIA participated in the development of HERSCHEL’s PACS instrument, a Dimensions: About 7.5 m high and 4 m wide. Among those, the 2009.

The European Space Agency's Herschel Space Observatory (formerly called Far Infrared and Sub-millimetre Telescope or FIRST) flew the largest single mirror ever built for a space telescope. By the end of its life, Herschel had collected a huge amount of data, and its observations are helping astronomers to understand the Universe – particularly how stars form and how galaxies grew and evolved over cosmic time. First maintain the low temperature. To achieve its scientific goals, HERSCHEL is equipped with a 3.5 m Current estimates of the
