Earth Image by Galileo Spacecraft   11.12.1990  NASA

Description: This color image of the Earth was obtained by the Galileo spacecraft at about 6:10 am PST. The color composite used images taken through the red, green and violet filters. South America is near the center of the picture, and the white, sunlit continent of Antarctica is below. Picturesque weather fronts are visible in the South Atlantic, lower right. This is the first frame of the Galileo Earth spin movie, a 500-frame time-lapse motion picture showing a 25-hour period of Earth's rotation and atmospheric dynamics.

Earth in Ultraviolet from Apollo 16 in 1972

Earth photographed by UV camera    21. April 1972    NASA  commons on flikr

Description: A color enhancement of an ultraviolet photograph of the geocorona, a halo of low density hydrogen around the Earth. Sunlight is shining from the left, and the geocorona is brighter on that side. The UV camera was operated by Astronaut John W. Young on the Apollo 16 lunar landing mission.

The milkyway in different wavelengths

Gamma-Ray (Fermi All Sky Survey) high-energy: 10 keV – 300 GeV
X-Ray (ROSAT All Sky Survey)  high-energy: 0.1 to 2 keV
The Visual Sky (DSS / Wikisky) 1 – 10 eV  the visible electromagnetic spectrum
H-Alpha (WHAM / SHASSA / VTSS / Finkbeiner)  Hydrogen gas: 656.3 nanometres wavelength
Far Infrared (IRAS)  infrared emission from galaxies and warm dust called infrared cirrus: 12, 25, 60, 100 µm (micrometre)
Microwave (Planck)  nine microwave wavelength bands ranging from 10mm to 0.35mm.  
As well as seeing the oldest light in the Universe, it also sees gas and dust within our own Galaxy.
Radio (Haslam)  408MHz   electrons radiation, emission from the milkywaydisk, remnants of nearby ancient supernova and distant radio galaxies.
