资料图 北极光视觉盛宴

　　Spectacular: The Northern Lights bursting into a spectacular display of purple in Norway 　　恍如隔世：在挪威一处湖泊上空拍摄到的超强紫色北极光。 　　The display was captured early yesterday morning by ?ystein Lunde Ingvaldsen, who grabbed his camera when he saw what was happening outside his window at B? in Vester?len, Norway. Green, as here, comes from oxygen molecules excited by geomagnetic activity.

　　这场宛如“盗梦空间”般的视觉盛宴原来是一位来自挪威的摄影师捕捉到的一处在湖面上的北极光奇观。瞧，天空呈现出魔幻般神奇的“梦幻颜色”，一股翠绿色的的“光晕”如童话般似的浮现在空中，倒映在湖里。据悉，这种梦幻般的北极光是由于太阳表面发生剧烈爆发活动而引起的。
