What are infrared telescopes?
Infrared telescope is one that examines infrared (IR) radiation emitted by astronomical bodies. Infrared radiation is part of the electromagnetic spectrum between visible light and microwaves. This part of the spectrum can be roughly divided into shorter wavelengths almost IR and longer far. Traditional optical telescopes are able to observe almost IR. Specially designed infrared telescopes are usually used to observe on wavelengths distant IR. Infrared binoculars based on Earth are located at a high altitude in the arid climate. Infrared radiation is less energy than visible light and is particularly subjected to absorbing atmospheric water vapor. A small distant IR radiation makes it an atmosphere. Telescope James Maxwell Telescope (JCMT) is an infrared telescope built at the Maun Kea observatory in Hawaii at an altitude of 13,425 feet (4092 m). Originally they were transferred at the top with a balloon. The current versions are equipped in the bodies of the aircraft. StratosphericThe Infrared Astronomy (Sofia) Observatory is built into the Boeing 747. This device contains a primary mirror of 9 feet (2.7 m).
Deployment of infrared telescopes in space eliminates the problem of atmospheric absorption. Infrared astronomical satellite (IRAS) was the first cosmic telescope to explore the sky on infrared wavelengths. A newer space IR binoculars were an explorer of an infrared wide field survey (wise). It was launched in 2009 and remained in operation until 2011. Infrared binoculars based on space usually have a short life because the required coolant is rapidly exhausted.
In the heart of each of these systems, it is an astronomical mirror of the timber to collect radiation and reflect it into the observation point. Various tools can be used in observation, infrared camera and infrared state detectors. OnceThe biggest challenges in designing and implementing an infrared telescope include the problem of cooling. The instrumentation must be cooled at several degrees of absolute zero. At warmer temperatures, it disrupts radiation from the binoculars with observation.
The purpose of observing the distant IR is to reveal what cannot be seen in a visible light. Clouds of dust and gas in our own and neighboring galaxies emit far IR. Star kindergartens can be detected by heat closing the protostars before they begin to emit visible light. Infrared telescopes extend our view of visible wavelengths, as well as radioxyopes expand it for infrared.
