[漢羅] ZTF 彗星 去拄著 ATLAS 彗星

彗星 C/2022 E3 (ZTF 彗星) 飛過 地球北天 ê 時陣，已經無遐爾光矣。 這張相片就是伊 kah 另外一粒 彗星 C/2022 U2 (ATLAS 彗星) ê 合影。 這張相片是 2 月 6 號 tī 德國 ê Bavarian 樹林翕--ê。 這个天星滿滿 ê 天區是 tī 御夫座 ê 方向，視野有 2.5 度闊。 這兩粒彗星是 tī 2022 年 ê 巡天計畫「ZTF 凌星觀測儀器」kah「ATLAS 小行星挵地球 ê 最後警報系統」ê 時陣 揣著--ê。 ZTF 這粒 長週期彗星 頂個月才行到近日點，這馬已經欲離開太陽矣。 ATLAS 彗星是閣較暗，伊 1 月 29 才接近咱這粒 ê 美麗地球。 伊彼陣 kah 地球 ê 距離是 4.6 光分。 是講 ZTF 彗星 tī 2 月 2 號彼陣 kah 地球 ê 距離是 2.4 光分。 ZTF 彗星進前猶會當用目睭直接看，伊 ê 尾溜實在是生了袂䆀。 毋過這粒 ATLAS 彗星，就無遮爾媠 ê 尾溜矣。 這兩粒彗星攏有足明顯 ê 青色彗鬚，這是雙原子炭分子去予日光激發產生 ê 螢光。 ZTF 彗星這馬是雙筒千里鏡上好 ê 觀測目標，因為伊紲落來會迒過地球 ê 天頂。 Eng 暗伊會出現 tī 明亮 ê 火星附近。

[English] ZTF meets ATLAS

Fading as it races across planet Earth's northern skies comet C/2022 E3 (ZTF) shares this telescopic frame with comet C/2022 U2 (ATLAS). Captured on the night of February 6 from a garden observatory in Germany's Bavarian Forest, the starry field of view toward the constellation Auriga spans about 2.5 degrees. Discovered by sky survey projects in 2022 (the Zwicky Transient Facility and the Asteroid Terrestrial-impact Last Alert System these long-period comets are outbound, reaching perihelion just last month. The much fainter comet ATLAS made its closest approach to our fair planet on January 29 at a distance of about 4.6 light-minutes, compared to a mere 2.4 light-minutes for comet ZTF on February 2. This comet ATLAS lacks the well-developed tails of the formerly naked-eye comet ZTF. But both comets sport greenish tinted comas, emission from diatomic carbon molecules fluorescing in sunlight. Continuing its dash across planet Earth's sky, the good-binocular comet ZTF will appear close to bright planet Mars tonight.
