To an ordinary person the atmosphere may look beautiful with the glowing sunlight, but to an astronomer the atmosphere causes various effects which includes distortion, reddening,refraction etc, which causes a blur vision of space when viewed through a telescope. This is problem NASA overcame and launched the Hubble space telescope in space.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
