[漢羅] 雷神 Thor ê 頭盔

雷神 Thor 毋若有 專屬 ê 日子（拜四），嘛是天堂 ê 頭盔。 咱一般攏 kā NGC 2359 叫做 雷神 Thor ê 頭盔。 伊是一个帽仔形 ê 宇宙雲，閣有兩支翼股。 雷神 Thor ê 頭盔有 30 光年闊，tùi 北歐神 來講嘛是有夠大 ê。 實際上，這个宇宙崁蓋較成是一个 星際氣泡，是去予氣泡中心一粒明亮、大質量恆星 ê 高速恆星風吹出來 ê。 中心恆星是 Wolf-Rayet 星，伊是 足燒 ê 巨恆星，是 超新星 前期足短 ê 演化階段。 NGC 2359 離 咱有 15000 光年遠，to̍h tī 大犬 座 ê 方向。 這張 遮爾清楚 ê 影像 是濫幾若款無仝 ê 觀測資料，有闊頻 kah 狹頻 濾片 ê 資料。 內底毋若有 一般看著 ê 影像，嘛有 星雲 雲絲 ê 清楚結構。 雷神 Thor ê 頭盔 中心 ê 恆星，閣紲落來幾若千年了後，應該會 爆炸，變做壯觀 ê 超新星。

[English] Thor's Helmet

Thor not only has his own day (Thursday), but a helmet in the heavens. Popularly called Thor's Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing-like appendages. Heroically sized even for a Norse god, Thor's Helmet is about 30 light-years across. In fact, the cosmic head-covering is more like an interstellar bubble, blown with a fast wind from the bright, massive star near the bubble's center. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. NGC 2359 is located about 15,000 light-years away toward the constellation of the Great Overdog. This remarkably sharp image is a mixed cocktail of data from narrowband filters, capturing not only natural looking stars but details of the nebula's filamentary structures. The star in the center of Thor's Helmet is expected to explode in a spectacular supernova sometime within the next few thousand years.
