[漢羅] Sh2-308: 海豬仔形 ê 恆星氣泡

是啥物星會當製造這个氣泡？ 毋是 氣泡正爿彼粒金爍爍 ê 星製造–ê。 嘛毋是太空大 海豬 製造–ê。 是藍色星雲中心彼粒，能量懸甲通人知 ê Wolf-Rayet 星 製造–ê。 Wolf-Rayet 星 ê 質量一般講–來是超過 20 倍 太陽質量，伊會歕出速度足緊 ê 粒子風，做出這个 外形 足出名 ê 星雲。 像這張影像內底這个恆星氣泡，大細是超過 60 光年闊，年歲有 7 萬歲矣，看起來敢若是海豬仔 ê 頭。 伊 ê 編號是 Sh2-308，嘛叫做 海豬仔頭星雲。 這粒氣體球離咱有 5000 光年遠，tī 天頂看–起來是 kah 規粒月娘 差不多大，是講伊較暗。 這張 影像 倒爿紅色色調 ê 星雲，可能是 ùi 仝這粒 Wolf-Rayet 星 發射出來–ê 能量較懸 ê 輻射光 kā 激發、創出這个外形–ê。

[English] Sh2-308: A Dolphin Shaped Star Bubble

Which star created this bubble? It wasn’t the bright star on the bubble’s right. And it also wasn’t a giant space dolphin. It was the star in the blue nebula’s center, a famously energetic Wolf-Rayet star. Wolf-Rayet stars in general have over 20 times the mass of our Sun and expel fast particle winds that can create iconic looking nebulas. In this case, the resulting star bubble spans over 60 light years, is about 70,000 years old, and happens to look like the head of a dolphin. Named Sh2-308 and dubbed the Dolphin-Head Nebula, the gas ball lies about 5,000 light years away and covers as much sky as the full moon – although it is much dimmer. The nearby red-tinged clouds on the left of the featured image may owe their glow and shape to energetic light emitted from the same Wolf-Rayet star.
