[漢羅] Kah ZTF 彗星 ê 軌道面交叉

這張 tī 美國加州 六月湖 ê 暗暝翕 ê 望遠鏡影像，是 北方夜空 目前 ê 主角，彗星 C/2022 E3 (ZTF 彗星)。 是講 ZTF 彗星 這幾工已經變甲 愈來愈光 矣，伊會 tī 2 月 1 號這工行到離地球上倚彼點。 這張相片是 tī 1 月 23 翕--ê，這个時陣 ê 地球，差不多是行到 kah 長週期彗星 ZTF 彗星 ê 軌道面交叉前後。 ZTF 彗星 tī 伊 ê 軌道 leh 行 ê 時陣，伊較闊、較白 ê 塗粉尾溜攏是彎曲--ê，而且這个 扇形 ê 尾溜是向離開太陽 ê 方向拍開。 地球 ê 視角 tī 行到 kah 彗星 軌道面 交叉前後 ê 時陣，會看著 扇形 ê 塗粉尾溜出現 tī 青色彗鬚 ê 兩爿。 按呢會予 ZTF 彗星 看起來閣有一條引人注目 ê 倒反彗尾（倒爿彼个彗尾）。 受著太陽活動 ê 影響，彗星較狹 ê 離子尾溜嘛伸 tùi 正爿 ê 對角方向去。 這條尾溜 ê 長度差不多佔視野範圍 ê 3 度闊。

[English] Comet ZTF: Orbital Plane Crossing

The current darling of the northern night, Comet C/2022 E3 ZTF is captured in this telescopic image from a dark sky location at June Lake, California. Of course Comet ZTF has been growing brighter in recent days, headed for its closest approach to Earth on February 1. But this view was recorded on January 23, very close to the time planet Earth crossed the orbital plane of long-period Comet ZTF. The comet's broad, whitish dust tail is still curved and fanned out away from the Sun as Comet ZTF sweeps along its orbit. Due to perspective near the orbital plane crossing, components of the fanned out dust tail appear on both sides of the comet's green tinted coma though, to lend Comet ZTF a visually striking (left) anti-tail. Buffeted by solar activity the comet's narrower ion tail also streams away from the coma diagonally to the right, across the nearly three degree wide field of view.
