[漢羅] Leonard 彗星 ê 長尾溜

Leonard 彗星 是 2021 年上光 ê 彗星。 這兩張相片是 tī 智利 Atacama 沙漠 ê 天頂翕 ê，彗星 to̍h tī 這兩張相片 ê 倒爿下跤遐。 一月 3 號是 Leonard 彗星 ê 近日點，伊這馬當 leh 飛過去，彗尾嘛愈來愈長，愈來愈看會著。 這是 kā 闊幅鏡頭翕 ê 幾若張相片疊做一張 ê（用烏白相片是欲予這个對比閣較明顯）。 按呢翕，是為著欲追蹤複雜 ê 離子尾溜。 是講，這个尾溜迒過天頂 60 度闊，實在是有夠長 ê 啦！ 木星嘛足光 ê，tī 正爿下跤 ê 地平線附近爍咧爍咧。 這款物質是 ùi Leonard 彗星 ê 核心 蒸發出來 ê。 這差不多有 1 公里闊，內底有足濟沙塗、岩石、kah 冰。 這寡物件去予太陽光照甲面頂 ê 離子氣體 leh 發光，產生長長 ê 尾溜。 最近幾若禮拜 彗核 受著太陽風 kah 磁場 ê 影響，有當時仔會突然間爍一下。 這嘛造成彗尾產生無規則、彎彎曲曲 ê 尾溜。 Leonard 彗星到近日點猶閣有幾若工，伊會繼續 遮爾活跳跳。 彗星這馬 tī 太陽系黃道面 ê 南爿，掃過南天 ê 顯微鏡座。

[English] The Further Tail of Comet Leonard

Comet Leonard, brightest comet of 2021, is at the lower left of these two panels captured on December 29 in dark Atacama desert skies. Heading for its perihelion on January 3 Comet Leonard's visible tail has grown. Stacked exposures with a wide angle lens (also displayed in a reversed B/W scheme for contrast), trace the complicated ion tail for an amazing 60 degrees, with bright Jupiter shining near the horizon at lower right. Material vaporizing from Comet Leonard's nucleus, a mass of dust, rock, and ices about 1 kilometer across, has produced the long tail of ionized gas fluorescing in the sunlight. Likely flares on the comet's nucleus and buffeting by magnetic fields and the solar wind in recent weeks have resulted in the tail's irregular pinched and twisted appearance. Still days from its closest approach to the Sun, Comet Leonard's activity should continue. The comet is south of the Solar System's ecliptic plane as it sweeps through the southern constellation Microscopium.
