[漢羅] 哈雷彗星 ê 塗粉、火星 ê 塗粉、kah 銀河系

5 月初 ê 時陣，有一大陣 宇宙塗粉粒 tī 夜空飛過。 這是 週期性彗星 哈雷彗星 留落來 ê 屑仔 流。 地球逐年行過 這寡屑仔流 ê 時陣，就會產生 寶瓶座 η 流星雨。 毋過，今年 5 月 ê 時陣，寶瓶座 η 流星雨上濟 ê 時陣，會因為拄著月圓，煞看無遐爾明。 是講舊年 5 月，出現 哈雷彗星 塗粉流 彼站仔 ê 透早，無去予月光影響著。 這張組合相片是 kā 2022 年 4 月 28 到 5 月 8 號之間 tī 智利 San Pedro de Atacama 天頂 紀錄落來 ê 寶瓶座 η 流星雨影像。 攏總有翕著 90 粒左右 ê 流星，in ê 輻射點 是 tī 寶瓶座。 弧形 ê 銀河中心 tī 天猶袂光進前，迒過南半球天頂。 Ùi 地平線 peh 起來、薄薄 ê 光帶是黃道光，這是太陽系黃道面頂懸 ê 塗粉去予日光散射產生 ê 光。 行 tī 黃道頂懸，kah 黃道光做伙出場 ê 行星，是 足光 ê 金星、木星、火星、kah 土星。 是講最近科學家發現講，火星本身 嘛有可能是製造黃道塗粉 ê 來源之一，這寡塗粉會 tī 地球天頂產生 黃道光。

[English] Halley Dust, Mars Dust, and Milky Way

Grains of cosmic dust streaked through night skies in early May. Swept up as planet Earth plowed through the debris streams left behind by periodic Comet Halley, the annual meteor shower is known as the Eta Aquarids. This year, the Eta Aquarids peak was visually hampered by May's bright Full Moon, though. But early morning hours surrounding last May's shower of Halley dust were free of moonlight interference. In exposures recorded between April 28 and May 8 in 2022, this composited image shows nearly 90 Eta Aquarid meteors streaking from the shower's radiant in Aquarius over San Pedro de Atacama, Chile. The central Milky Way arcs above in the southern hemisphere's predawn skies. The faint band of light rising from the horizon is Zodiacal light, caused by dust scattering sunlight near our Solar System's ecliptic plane. Along the ecliptic and entrained in the Zodiacal glow are the bright planets Venus, Jupiter, Mars, and Saturn. Of course Mars itself has recently been found to be a likely source of the dust along the ecliptic responsible for creating Zodiacal light.
