Peeking into SEST

The Swedish-ESO Submillimetre Telescope (SEST) was a radio telescope of diameter 15 metres located at the La Silla Observatory in Chile. The telescope was built in 1987 as a combined project between ESO and Onsala Space Observatory, with contributions from Finland and Australia. It was then the only large telescope for submillimetre astronomy in the southern hemisphere. It was decommissioned in 2003.

The telescope was used for single-dish observations of a wide range of astronomical objects, especially the Galactic centre and the Magellanic Clouds and for interferometric observations at millimetre wavelengths.

In 1995 observations made with SEST showed that the Boomerang Nebula is the coldest known location in the universe, with a temperature lower than the background radiation.
