[漢羅] IC 4628：九節蝦星雲

Tī 心宿二 ê 南方，厚星雲 ê 天蠍座 尾溜，有一个 發射星雲 IC 4628。 這个星雲就 tī 幾若百萬粒 高溫、大質量 少年恆星邊仔。 看袂著 ê 紫外光 kā 星雲照甲 kā 原子內底 ê 電子激發出來。 電子落尾會 kah 原子重新組合，產生 看會著 ê 星雲光，這主要是發生 tī 水素原子 ê 反應，會發出紅色 ê 發射線。 照估計 ê 距離 6000 光年來算，這區 差不多有 250 光年 闊，按呢是超過 3 粒月娘 tī 天頂 ê 範圍。 這个星雲嘛去予澳洲天文學家 Colin Stanley Gum kā 編做 Gum 56，毋過愛食海產 ê 天文愛好者 tùi 這个宇宙雲 較知影 ê 名 可能是 九節蝦 星雲。 這張 優雅 ê 彩色影像 是 4 月 ê 時陣 tī 智利 ê Rio Hurtado 開幾若暗 ê 時間翕--ê 新 ê 天文相片。

[English] IC 4628: The Prawn Nebula

South of Antares, in the tail of the nebula-rich constellation Scorpius, lies emission nebula IC 4628. Nearby hot, massive stars, millions of years young, irradiate the nebula with invisible ultraviolet light, stripping electrons from atoms. The electrons eventually recombine with the atoms to produce the visible nebular glow, dominated by the red emission of hydrogen. At an estimated distance of 6,000 light-years, the region shown is about 250 light-years across, spanning over three full moons on the sky. The nebula is also cataloged as Gum 56 for Australian astronomer Colin Stanley Gum, but seafood-loving deep sky-enthusiasts might know this cosmic cloud as the Prawn Nebula). The graceful color image is a new astronomical composition taken over several nights in April from Rio Hurtado, Chile.
