13 P/Olbers 彗星每隔 70 年左右就會造訪一次內太陽系,它最近一次到達近日點或最接近太陽是在 2024 年 6 月 30 日。現在,這顆哈雷型彗星正在返回遙遠的奧爾特雲的航程中,在這裡記錄的是它掠過捷克歷史悠久的庫內蒂採城堡上空的北方夏夜天空。除了寬大的塵埃尾部和更明亮的彗星彗尾外,這顆彗星的長離子尾部受到來自太陽的風暴和狂風的衝擊,在彗星和天空的跟蹤曝光以及 7 月 28 日記錄的前景景觀的固定曝光的合成照片中顯現出來。彗星位於城堡外約 16 光分處,在大熊座北部下方微弱的背景恆星中清晰可見。這座山頂城堡可以追溯到 15 世紀,而海因裡希-奧爾伯斯(Heinrich Olbers)發現這顆彗星則是在 1815 年。奧伯斯彗星在日落後的西北部低空被拍攝到,目前,地球上的觀星者可以用望遠鏡和雙筒望遠鏡欣賞到這顆彗星。 13 P/Olbers 彗星的下一個近日點將在 2094 年。
原文:A visitor to the inner solar system every 70 years or so Comet 13P/Olbers reached its most recent perihelion, or closest approach to the Sun, on June 30 2024. Now on a return voyage to the distant Oort cloud the Halley-type comet is recorded here sweeping through northern summer night skies over historic Kunetice Castle, Czech Republic. Along with a broad dust tail, and brighter coma, this comet's long ion tail buffeted by storms and winds from the Sun, is revealed in the composite of tracked exposures for comet and sky, and fixed exposures for foreground landscape recorded on July 28. The comet is about 16 light-minutes beyond the castle and seen against faint background stars below the northern constellation Ursa Major. The hilltop castle dates to the 15th century, while Heinrich Olbers discovered the comet in 1815. Captured here low in northwestern skies just after sunset Comet Olbers, for now, offers skywatchers on planet Earth rewarding telescopic and binocular views. Comet 13P/Olbers next perihelion passage will be in 2094.
