这颗崎岖的小行星沉浸在令人毛骨悚然的绿光中，似乎拥有令人惊叹的瀑布和一座不可思议的高山。当然是地球。11月9日晚，冰岛西部Kirkjufell山区的数码相机拍摄到了以最低点为中心的360度马赛克。闪烁的北极光提供了淡绿色的照明。11月初，太阳活动震动了地球的磁层，并产生了强烈的地磁风暴，导致了强烈的极光现象。Kirkjufell山本身位于立体投影的圆形地平线的顶端。北半球的天文观测者将会认出熟悉的北斗七星就在基尔朱菲尔峰的上方。在右下角，紧凑的昴宿星团和真正巨大的行星木星也在这颗小行星的夜空中闪耀。

Immersed in an eerie greenish light, this rugged little planet appears to be home to stunning water falls and an impossibly tall mountain. It's planet Earth of course. On the night of November 9 the nadir-centered 360 degree mosaic was captured by digital camera from the Kirkjufell mountain area of western Iceland. Curtains of shimmering Aurora Borealis or Northern Lights provide the pale greenish illumination. The intense auroral display was caused by solar activity that rocked Earth's magnetosphere in early November and produced strong geomagnetic storms. Kirkjufell mountain itself stands at the top of the stereographic projection's circular horizon. Northern hemisphere skygazers will recognize the familiar stars of the Big Dipper just above Kirkjufell's peak. At lower right the compact Pleiades star cluster and truly giant planet Jupiter also shine in this little planet's night sky.
