说明: 在这片偶然拍下的山顶景观里,暗去的暮光天空中,渲染着粉红色的柔和辉光。这幅摄于冰点以下气温的精心规画影像,呈现了11月14日在山脉隘口见到的崎岖雪峰,下方则是位在义大利多罗迈高山里的阿尔塔巴迪亚区之拉维拉村。在山凹的小村灯火上方,可见到悬在北方地平面上方的北斗七星。不过,影像中最让人讚叹不已的,是明亮的火流星。它在相机进行拍摄时,意外的在熟悉的北斗七星下方,从东向西飞掠而过。事实上,除了在广大的欧洲地区,各处都有这颗火流星的目击报告之外,它更是美国流星协会国际流星组织,历年来最多观测报告的火流星事件。针对这颗流星在德国上空的流星痕之量测指出,它最可能是源自11月最活跃的金牛座流星雨辐射点之流星。金牛座流星雨的源头,则是来自恩克彗星碎片。

Explanation: The sky glowswith soft pinkish colors of fading twilightin this serendipitous mountaintop vista. Taken in subfreezing temperatures, the thoughtfully composed photoshows snowy, rugged peaks seen from a mountain pass on November 14.Below liesthe village of La Villa, Alta Badia in Italy's DolomiteAlps.Above the nestled village lights,the constellation Ursa Major hangs over the northern horizon.But most stunning is the intense fireball meteor.It was captured during the camera's exposure by chance as itflashed east to west across thenorthern horizon, under Ursa Major's familiar Big Dipper asterism.In fact, sightingsof this major fireball meteor were widely reported in European skies, themostreported fireball event ever for planet Earth'sAmericanMeteor Society and theInternationalMeteor Organization.The meteor's measured track over Germany is consistent with its origin nearthe active radiant ofNovember's Taurid Meteor Shower.Taurid meteors are associated with dust fromEncke's comet.
