NASA on Wed­nes­day re­leased this stun­ning video of the Au­rora Aus­tral­is, or South­ern Lights, taken from the In­ter­na­tion­al Space Sta­tion on Sept. 17. The foot­age was cap­tured as the space sta­tion passed from south of Mad­a­gas­car to just north of Aus­tralia over the In­di­an Ocean. The au­rora ap­pears when ions in the sol­ar wind col­lide with atoms of oxy­gen and ni­tro­gen in the up­per at­mo­sphere, emit­ting light as the ex­cited atoms re­turn to their ori­gin­al en­ergy level.
