File:The Milky Way by JP Metsavainio from Taurus the Bull to Cygnus the Swan.jpg

Within a region of 125 arc minutes, stretching from the constellation Taurus the Bull to the constellation Cygnus the Swan, Finnish astrophotographer J-P Metsavainio took 12 years to photograph and stitch together a deep and detailed panorama of our Milky Way galaxy stretching across the night sky.

The Milky Way panorama final image stretches over 125 degrees of sky. Metsavainio made this photo mosaic using special filters, only letting certain wavelengths through. As a result, the colors you can see in this image come from light emitted by 3 ionized elements, meaning elements that have lost one or more electrons in their atoms; hydrogen (H-alpha), sulphur (S II) and oxygen (O III).
