What Are Space Observatories?
Space observatories are telescopes or instruments located in outer space to observe distant planets, galaxies, and other astronomical phenomena. They provide a clearer view of the universe by avoiding the Earth's atmosphere, which can distort and block light.
-
Hubble Space Telescope: Launched in 1990, the Hubble Space Telescope has provided some of the most detailed images of space. It orbits Earth at about 547 kilometers above sea level.
-
James Webb Space Telescope: Scheduled for launch in 2021, this telescope will be the largest and most powerful ever sent into space. It aims to study the formation of stars and galaxies.
Why Are Space Observatories Important?
Space observatories have revolutionized our understanding of the universe. They allow scientists to gather data that would be impossible to collect from Earth.
-
Clearer Images: Space observatories avoid atmospheric distortion, providing clearer and more detailed images.
-
Wider Spectrum: They can observe a broader range of wavelengths, including ultraviolet and infrared, which are absorbed by Earth's atmosphere.
