Fairytale NEOWISE

Explanation: Comet dust falls through a twilight sky in this dream-like scene, but it’s not part of a fairytale movie. Still, Castle Neuschwanstein, nestled in the Bavarian Alps, did inspire Disneyland’s Sleeping Beauty Castle. Captured on July 20, the bright streak above the castle towers is likely a Perseid meteor. Though it peaks near mid-August, the annual summer meteor shower is active now. The meteor trail over the fairytale castle can be traced back to the shower’s radiant in the heroic constellation Perseus off the top right of the frame. Perseid meteors are produced by dust from periodic Comet Swift-Tuttle. With its own broad dust tail now sweeping through northern skies the celestial apparition above the distant horizon is planet Earth’s current darling, Comet NEOWISE.

说明: 在这片梦境般的影像里,彗星碎片掠过暮光时分的天空,然而这不是童话电影里的场景。话虽如此,座落在巴伐利亚阿尔卑斯山脉里的新天鹅堡,的确是迪士尼电影里,睡美人居住的城堡之原型。在这张摄于7月20日的影像里,城堡钟塔上空的明亮线形光痕,很可能是英仙座流星。因为这道掠过城堡上空的流星痕,可以回溯到位在视野右上角外头的英仙座之辐射源。虽然英仙座流星雨的极大期是在8月中,不过现在它已逐渐活跃。英仙座流星的前身,是周期彗星史威福-塔托释出的尘埃微粒。在影像中,曳着宽广尘尾掠过北天的幽灵状天体,则是地球住民目前最钟爱的NEOWISE彗星。
