Time-Lapse auroras over Norway
NASA’s feature for their daily “Astronomy Picture of the Day” today is breathtaking. Instead of a photograph, they posted this time lapse shot by Terje Sorgjerd “in and around Kirkenes and Pas National Park bordering Russia” during -25 degree Celsius (-13 degree Fahrenheit) temperatures. NASA explains:
….earlier this month when one of the largest auroral displays in recent years appeared over northern locations like the border between Norway and Russia. Pictured in the above time-lapse movie, auroras flow over snow covered landscapes, trees, clouds, mountains and lakes found near Kirkenes, Norway. Many times the auroras are green, as high energy particles strike the Earth’s atmosphere, causing the air to glow as electrons recombine with their oxygen hosts. Other colors are occasionally noticeable as atmospheric nitrogen also becomes affected. In later sequences the Moon and rising stars are also visible. With the Sun expected to become ever more active over the next few years, there may be many opportunities to see similarly spectacular auroras personally, even from areas much closer to the equator.
Sorry supermoon, the auroras will always beat you in the Night Sky Beauty Pageant contests.
