1. Observatories Across the Electromagnetic Spectrum
The Earth's atmosphere absorbs ultraviolet light, so ultraviolet astronomy must be done using telescopes in space. Other than carefully-select materials for ...
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
2. Why are telescopes placed in space above earths atmosphere? - Answers
May 14, 2022 · Ground based telescopes are not as effective at these observations because infrared light is largely blocked by water in Earth's atmosphere. Why ...
Scintillation. Our atmosphere is in continous motion. Warm air changes the angle of EM waves passing through a little bit differently than cold air. The constant motion causes constant shifts in the waves. This is why the stars seem to twinkle. In space, there is no such distortion. Space borne telecopes see far clearer images because of this.
