The spectroscopy of excited O*6+ and O*7+ SW ions is investigated as a diagnostic of astrophysical plasmas. The emission spectra of highly charged oxygen ions, induced by the Solar Wind (SW) interacting with the heliospheric H and He gas and cometary and planetary atmospheres, are calculated. Absolute and relative intensities of the X-ray emission lines induced in the charge-exchange collisions of bare O8+ and hydrogenic O7+ oxygen ions with neutral atoms are computed and compared with the results of observations with the Chandra and XMM-Newton X-ray telescopes. Charge- exchange X-ray and EUV emissions produced by the slow and fast solar winds are predicted. An analysis of X-ray photon spectra detected from the interstellar gas and cometary and planetary atmospheres is carried out to determine the parameters of the interacting SW plasma and neutral gas. The contribution of charge- exchange mechanism of O*6+ and O*7+ emissions to the soft X-ray background is discussed.
