Telescopes that observe the infrared spectra of other planets must be placed in space because Earth's atmosphere absorbs most infrared wavelengths, blocking them from reaching ground-based telescopes. ;
Telescopes observing infrared spectra of planets must be in space because Earth's atmosphere absorbs much of the infrared radiation. Key gases like water vapor, ozone, and carbon dioxide contribute to this absorption. By placing telescopes in orbit, astronomers can observe the full range of infrared light from these planets, enhancing their research capabilities.
