“Swedish-ESO Submillimetre Telescope”的意思、由来-开放百科全书

The Swedish-ESO Submillimetre Telescope (SEST) was a 15-metre diameter radio telescope 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.^[1] It was then the only large telescope for submillimetre astronomy in the southern hemisphere.^[2] It was decommissioned in 2003.^[3]

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.^[1]

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.^[4]^[5]
