Spectacular Aurora

09-28-2011 10:48 BJT

A NASA image captured from the International Space Station taken on Sept 26, 2011 shows
rare aurora appearing in red. The colours 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 atmosphere. This
produces a green photon, so most auroras 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. [Photo/Agencies]

Aurora Australis or "Southern lights" are seen in this picture captured by astronauts on
the International Space Station (ISS) with a digital camera while they passed over the
Indian Ocean, in this Sept 17, 2011 photograph. [Photo/Agencies]
