Image title	NASA image captured September 26, 2011Many aurora appear green, but sometimes— as in this image from the International Space Station — other colors such as red can appear. The colors depend on which atoms are causing the splash of light seen in the aurora. In most cases, the light comes when a charged particle sweeps in from the solar wind and collides with an oxygen atom in Earth’s atmosphere. This produces a green photon, so most aurora appear green. However, lower-energy oxygen collisions as well as collisions with nitrogen atoms can produce red photons -- so sometimes aurora also show a red band as seen here.Karen FoxNASA's Goddard Space Flight CenterCredit: NASA<b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html"rel="nofollow">NASA image use policy.</a></b><b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b>enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.
