Space-based observatories Observatory
space-based observatories telescopes or other instruments located in outer space, many in orbit around earth. space telescopes can used observe astronomical objects @ wavelengths of electromagnetic spectrum cannot penetrate earth s atmosphere , impossible observe using ground-based telescopes. earth s atmosphere opaque ultraviolet radiation, x-rays, , gamma rays , partially opaque infrared radiation observations in these portions of electromagnetic spectrum best carried out location above atmosphere of our planet. advantage of space-based telescopes that, because of location above earth s atmosphere, images free effects of atmospheric turbulence plague ground-based observations. result, angular resolution of space telescopes such hubble space telescope smaller ground-based telescope similar aperture. however, these advantages come price. space telescopes more expensive build ground-based telescopes. due location, space telescopes extremely difficult maintain. hubble space telescope ser
