This presentation is based on a 'Multi wavelength Milky Way' PDF by NASA (http://mwmw.gsfc.nasa.gov/images/mwmw_11a.pdf).
Visible light makes just a tiny fraction of the electromagnetic spectrum. Many space phenomena - like cosmic rays, supernova remnants, pulsars and ionized interstellar gas produce electromagnetic radiation in many different wavelengths - longer and shorter than those of the optical spectrum and thus invisible to the naked eye. In this presentation user can browse panoramas of The Milky Way galaxy based on several space and ground-based surveys conducted by NASA and other scientific institutions.
