Evolved Stars and Supernovae

The Herschel Space Observatory, launched by the European Space Agency on May 14th 2009 and named after the astronomer William Herschel, had a 3.5m diameter telescope, the largest ever sent into space and the first mirror made of silicon carbide to be used by a large space telescope. It has three scientific instruments on-board, for imaging and spectroscopy in the far-infrared and submillimetre wavelength regions (55-670 microns), all cooled to -269 Celsius, with more than 3000 litres of liquid helium needed to cool them up until liquid helium exhaustion on April 29th 2013. Further information about Herschel can be found here. The UCL Astrophysics Group has a major involvement in several Guaranteed Time Key Projects associated with Herschel's SPIRE and HIFI instruments. Results from some of these Key Projects are described in the links below.
