Which feature do space-based observatories like the Hubble Space Telescope bypass?
Answer
Earth's atmosphere
Space-based observatories, such as the Hubble Space Telescope, are specifically positioned above Earth's atmosphere to avoid the limitations imposed by the lower atmosphere. The atmosphere causes blurring and distortion, often referred to as 'seeing,' which limits the resolution of even the largest ground-based instruments. By operating in space, these instruments eliminate this atmospheric variable, providing unparalleled clarity and enabling observations across wavelengths, like ultraviolet light, that are heavily absorbed by the atmosphere.
