On May 29 , this photo was rent on the International Space Station by a NASA astronaut on Expedition 23 . It show aurora australis , the southern Lights , zigzagging towards the South Pole .
Here ’s NASA ’s background on this gorgeous , neon green aurora :
These ever - shift display of coloured ribbons , mantle , ray of light , and spots are most seeable near the North ( aurora borealis ) and South ( aurora australis ) Poles as bill particles streaming from the Sun ( the solar wind ) interact with Earth ’s magnetic field , resulting in collisions with atom of oxygen and nitrogen in the upper atmosphere . The atoms are stimulate by these collisions , and typically emit photons as a means of fall to their original Department of Energy state . The photon form the aurora that we see . The most commonly observed color of aurora is green , triggered by photons ( light ) emitted by unrestrained O atoms at wavelengths revolve around at 0.558 micrometers , or millionths of a m [ … ]
While aurora are in general only visible near to the pole , stern magnetic tempest affect the Earth ’s magnetic theatre of operations can agitate them towards the equator . This salient aurora image was taken during a geomagnetic violent storm that was most in all likelihood get by a coronal mass expulsion from the Sun on May 24 , 2010 . The ISS was located over the Southern Indian Ocean at an ALT of 350 kilometre , with the astronaut observer most likely seem towards Antarctica ( not visible ) and the South Pole .
Forget Pink Floyd Fridays at the province planetarium — nature provides all the trippy laser displays you could ever demand for .
