What is meant by space observation? Why is it importanant

Dear Students 


Space observatory i an artificial satellite equipped  instrument designed for the observation and study of objects and phenomena in outer space or to study the earth 's atmosphere. Thus the observation and study of the space is called space observations .
Astronomical observations from the earth's surface are hampered by filtering and distortion of electromagnetic radiation by the earth's atmosphere , and light pollution from artificial light sources on earth. The only two wavelength ranges of the electromagnetic spectrum that are not severely attenuated by the atmosphere are the visible light and radiowave regions. The infrared, ultraviolet, x ray and gamma ray regions of the spectrum are highly blocked. Space observatories operate from beyond the earth's atmosphere and are therefore not hampered by atmospheric interferences. 
It is important for frequency ranges outside the optical and radial windows.
It is important to have long running, continuous observations for forecasting and for research in space weather.
It is important to predict changes in earth's weather.
