NSF (1) – Aurora Australis
A selection of five galactic vista’s featuring the phenomenon ‘Aurora Australis‘ dancing high above the South Pole Telescope at Amundsen-Scott Station, Antarctica.
The Aurora Australis is the Southern Hemispherical equivalent of the Aurora Borealis or Northern Lights. Auroras occur when Solar Wind carrying charged particles from the Sun enter the upper atmosphere and are accelerated through Earth’s magnetic field. The Southern lights are less witnessed than there Northern counterpart, mainly due to the fact there’s much less inhabited land at high southern latitudes.

The photos are taken from the National Science Foundation (NSF) website’s multimedia gallery which is fantastic source of high res imagery, from Galactic Panorama’s to renderings of Computational Fluid Dynamics – suffice to say there’s some pretty trippy stuff, well worth a look: http://ow.ly/kabe
