[漢羅] ZTF 彗星 ê 尾溜

咱可能有機會用目睭直接看著 ZTF 彗星。 這粒大質量雪球 sī 舊年初發現--ê。 伊這馬 sī 愈來愈光，因為伊離太陽 kah 地球 sī 愈來愈倚矣。 彗星 C/2022 E3 (ZTF 彗星) 紲落來這禮拜會行到離太陽上倚 ê 位置。 時到伊就會變甲足光--ê，按呢北天 ê 觀星者 tī 好天 ê 暗暝，無雙筒千里鏡嘛看會著。 彗星 上歹名聲 ê 代誌 就是，in 若是愈倚太陽，伊 ê 輝度就愈歹預測。 這張影像是頂禮拜 tī 這个 美麗 ê 星場 翕--ê。 有 3 條藍色 ê 離子尾溜 伸到正爿頂懸，應該是多變 ê 太陽風 予 離子 ùi 堅凍 ê 彗核 噴出來 ê 結果。 彗星 ê 白色 塗粉尾溜 就較短，伸 tùi 倒爿頂懸去。 青光 是彗核，是 ùi 發光 ê 炭素氣體來--ê。 ZTF 彗星 應該會 tī 二月初彼陣行到離地球上倚 ê 位置，了後伊就會雄雄變暗去。

[English] Tails of Comet ZTF

Comet ZTF may become visible to the unaided eye. Discovered early last year, this massive snowball has been brightening as it approaches the Sun and the Earth. C/2022 E3 (ZTF) will be closest to the Sun later this week, at which time it may become visible even without binoculars to northern observers with a clear and dark sky. As they near the Sun, comet brightnesses are notoriously hard to predict, though. In the featured image taken last week in front of a picturesque star field, three blue ion tails extend to the upper right, likely the result of a variable solar wind on ions ejected by the icy comet nucleus. The comet's white dust tail is visible to the upper left and much shorter. The green glow is the comet's coma, caused by glowing carbon gas. Comet ZTF is expected to pass nearest the Earth in early February, after which it should dim dramatically.
