[漢羅] 幾若粒星系 kah 一粒彗星

這張 星系滿四界 ê 清楚望遠鏡影像 是 10 月 12 tī 美國加州六月湖天頂翕–ê。 這个天景有 2 度闊，就 tī 北天星座 獵犬座 ê 邊界。 Tī 倒爿頂懸彼个顯目 ê 星系是 NGC 4258，伊 to̍h chhāi tī 2350 萬光年遠 ê 所在，是一个大型捲螺仔星系，嘛叫做 Messier 106。 中央正爿頂懸彼个吸引咱目睭 ê 是側向捲螺仔星系 NGC 4217，伊就 tī 6000 光年遠 ê 所在。 編號 C/2023 H2 ê Lemmon 彗星 拄仔好行過 這个美麗 ê 視野，這是舊年 4 月 ùi Lemmon 山巡天計畫 ê 影像資料內底揣著 ê 彗星。 這粒彗星有顯目 ê 青色彗鬚，kah 一條狹狹暗暗 ê 離子尾溜，伸 tùi 這幅圖頂懸去。 這位 內太陽系 ê 人客 離咱才無夠 7 光分遠，用雙筒望遠鏡欲看猶真困難，毋過伊是愈來愈光矣。 編號 C/2023 H2 ê Lemmon 彗星 會 tī 10 月 29 行到近日點，就是離太陽上倚彼點，tī 11 月 10 號行到近地點，就是離咱地球上倚彼點。 伊 tī 北半球天頂出現 ê 時間嘛會 ùi 透早 變做暗暝。

[English] Galaxies and a Comet

Galaxies abound in this sharp telescopic image recorded on October 12 in dark skies over June Lake, California. The celestial scene spans nearly 2 degrees within the boundaries of the well-trained northern constellation Canes Venatici. Prominent at the upper left 23.5 million light-years distant is big, beautiful spiral galaxy NGC 4258, known to some as Messier 106. Eye-catching edge-on spiral NGC 4217 is above and right of center about 60 million light-years away. Just passing through the pretty field of view is comet C/2023 H2 Lemmon, discovered last April in image data from the Mount Lemmon Survey. Here the comet sports more of a lime green coma though, along with a faint, narrow ion tail stretching toward the top of the frame. This visitor to the inner Solar System is presently less than 7 light-minutes away and still difficult to spot with binoculars, but it’s growing brighter. Comet C/2023 H2 Lemmon will reach perihelion, its closest point to the Sun, on October 29 and perigee, its closest to our fair planet, on November 10 as it transitions from morning to evening northern skies.
