[漢羅] 彗星 Leonard kah 海翁星系

這張組合相片是 11 月 24 天光進前翕 ê，這陣 ê 彗星 Leonard (C/2021 A1) 掃過 北天兩个星系之間。 青色 ê 彗鬚是彗星 ê 塗粉尾溜，拄仔好射 tī 頂懸彼个 NGC 4631，海翁星系 ê 心臟區。 毋閣 NGC 4631 kah 下底 ê NGC 4656，棍仔球桮星系，是背景星系， tī 2500 萬光年遠 ê 所在。 這工，彗星離咱 ê 地球有 6 光分 ê 距離。 彗星 Leonard 離地球上近 ê 時陣猶未到（而且會離 金星 閣較近），伊會 tī 12 月 ê 時陣變閣較光。 這粒彗星這馬用雙筒望遠鏡 kah 細台望遠鏡 已經看會著矣。 這是伊上尾一擺拜訪內太陽系。 伊 ê 近日點，就是伊上倚太陽彼工，會 tī 1 月 3 號。

[English] Comet Leonard and the Whale Galaxy

Sweeping through northern predawn skies, on November 24 Comet Leonard (C/2021 A1) was caught between two galaxies in this composite telescopic image. Sporting a greenish coma the comet’s dusty tail seems to harpoon the heart of NGC 4631 (top) also known as the Whale Galaxy. Of course NGC 4631 and NGC 4656 (bottom, aka the Hockey Stick) are background galaxies some 25 million light-years away. On that date the comet was about 6 light-minutes from our fair planet. Its closest approach to Earth (and even closer approach to Venus still to come, Comet Leonard will grow brighter in December. Already a good object for binoculars and small telescopes, this comet will likely not return to the inner Solar System. Its perihelion, or closest approach to the Sun, will be on January 3, 2022.
