An orbiting infrared telescope (60 cm mirror) which successfully operated from launch in January 1983 until the supply of coolant ran out in November 1983. It was a collaborative mission between NASA, the Netherlands, and the UK, and mapped 95% of the whole sky in the wavelength bands 12, 25, 60, and 100 microns.

infrared; → excess.

infrared galaxy
  کهکشان ِ فروسرخ   
kahkešân-e forusorx (#)

Fr.: galaxie infrarouge   

A galaxy that emits most of its energy in the infrared region of the spectrum. Such galaxies are thought to have unusually high rates of star formation and are also described as → starburst galaxies.

infrared; → galaxy.

infrared imaging
  تصویرگری ِ فروسرخ   
tasvirgari-ye forusorx (#)

Fr.: imagerie infrarouge

The wavelengths range from about 0.8 → microns (μm) to about 1000 μm. See also: → near-infrared; → mid-infrared; → far-infrared; → submillimeter radiation.

infrared; → radiation.

Infrared Space Observatory (ISO)
  نپاهشگاه ِ فضایی ِ فروسرخ   
nepâhešgâh-e fazâyi-ye forusorx

Fr.: Satellite ISO   

A European Space Agency satellite which carried the most sensitive infrared telescope ever launched. It operated between November 1995 and April 1998 and made particularly important observations of the dusty regions of the Universe. ISO was equipped with four science instruments: an infrared camera (CAM), a long-wavelength spectrometer (LWS), a photo-polarimeter (PHT), and a short-wavelength spectrometer (SWS). The instruments jointly covered wavelengths from 2.5 to around 240 microns with spatial resolutions ranging from 1.5 arcseconds to 90 arcseconds. Its 60 cm diameter telescope was cooled by superfluid liquid helium to temperatures of 2-4 K. The mission was a great technical, operational and scientific success. During its routine operational phase, ISO successfully made some 30,000 individual imaging, photometric, spectroscopic, and polarimetric observations ranging from objects in our own solar system to the most distant extragalactic sources.

infrared; → space; → observatory.

infrared window
  روزنه‌ی ِ فروسرخ   
rowzane-ye forusorx (#)

Fr.: fenêtre infrarouge   

A range of infrared wavelengths to which the Earth's atmosphere is relatively transparent, and at which observations can be made from the ground. Infrared windows are found near wavelengths of 1.25, 1.65, 2.2, 3.6, 5.0, 10, 20, and 30 microns, and beyond 300 microns.

infrared; → window.
