Glossary term: Infrared Telescope

Description: An infrared telescope observes infrared light and is used for infrared astronomy. Infrared telescopes can be situated on the ground or in space. Observatories situated on Earth are limited in what they can observe by atmospheric absorption and infrared radiation emitted by the Earth's atmosphere, the telescope itself, and its surroundings. Space infrared telescopes do not need to deal with atmospheric absorption or infrared radiation from their immediate surroundings and can be shielded from the Sun and cooled, reducing the infrared radiation emitted by the telescope.
