COSMOlogical Structures On Medium Angular Scales
COSMOlogical Structures On Medium Angular Scales, Radio telescope at Teide Observatory, Spain
Description
COSMOS is a radio telescope at Teide Observatory designed to observe the cosmic microwave background radiation filling space. The instrument uses a rotating flat mirror and a specialized antenna to capture extremely faint radio signals from across the sky.
History
The observatory operated this instrument from 1998 to 2007 as one of its key tools for space research. During that period it collected scientific data that contributed to understanding the universe's earliest history.
Culture
The telescope contributed to international scientific understanding by mapping spatial variations in temperature of the 2.7K cosmic microwave background radiation.
Practical
The instrument was located at one of the world's leading high-altitude observatories above 2,000 meters with excellent sky visibility. This remote location provided minimal atmospheric interference and enabled highly precise observations of cosmic signals.
Did you know?
The system used a cryogenically frozen receiver unit to amplify the faintest signals reaching Earth from the coldest regions of the universe. This cooling technology was essential to detect the tiniest temperature variations in the cosmic radiation.
