NASA Astronomy Picture of the Day
In Green Company: Aurora over Norway
Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds -- mostly. On the third night of returning to same peaks, though, the sky not only cleared up but lit up with a spectacular auroral display. Arms went high in the air, patience and experience paid off, and the creative featured image was captured as a composite from three separate exposures. The setting is a summit of the Austnesfjorden (a fjord) close to the town of Svolvear on the Lofoten islands in northern Norway. The year was 2014. This year, our Sun is just passing solar maximum, the peak in its 11-year surface activity cycle. As expected, some spectacular auroras have recently resulted. Portal Universe: Random APOD Generator
