[漢羅] NGC 1499：加州星雲

加州皇后 ê 神祕島敢有 tī 太空中？可能無。 毋過這个分子雲拄仔好 kah 美國 加州 ê 外形有相-siâng。 咱 ê 太陽 to̍h 蹛 tī 銀河 ê 獵戶座手骨 內底，離 加州星雲 干焦差不多 1000 光年遠爾爾。 這个是發射星雲 ê 代表，嘛號做 NGC 1499，伊差不多有 100 光年 遐爾長。 Tī 這張 影像 內底，加州星雲上明顯 ê 光 to̍h 是紅色特徵光。 這是 水素 原子 kah 失去足久 ê 電子重新合併了後，閣去予高能 ê 恆星光 kā 離子化 了後，才發出 ê 色光。 這粒提供高能恆星光 ê 恆星，會 kā 大部份 ê 星雲氣體離子化。 伊 to̍h 是星雲正爿彼粒光閣高溫 ê 藍色恆星，英仙座 ξ。 Tùi 天文攝影師來講，加州星雲是一个定定 leh 翕–ê 目標。 伊會當用闊幅望遠鏡 tī 夜空 ê 英仙座 方向 揣著，離 畢宿星團 袂傷遠。

[English] NGC 1499: The California Nebula

Could Queen Calafia’s mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way’s Orion Arm, only about 1,000 light-years from the California Nebula. Also known as NGC 1499, the classic emission nebula is around 100 light-years long. On the featured image, the most prominent glow of the California Nebula is the red light characteristic of hydrogen atoms recombining with long lost electrons, stripped away (ionized) by energetic starlight. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei just to the right of the nebula. A regular target for astrophotographers, the California Nebula can be spotted with a wide-field telescope under a dark sky toward the constellation of Perseus, not far from the Pleiades.
