'''RCW 34'''（Gum 19）是一個位於[[船帆座]]HII區和[[發射星雲]]。RCW 34距離[[地球]]約8,200[[光年]]，以[[澳洲]][[天文學家]][[柯林·史丹利·古姆]]的名字命名<ref>{{Cite web|url=https://apod.nasa.gov/apod/ap060519.html|title=APOD: 2006 May 19 - The Gum Nebula|website=apod.nasa.gov|access-date=2018-11-17}}</ref>。

RCW 34星雲相對較暗。然而，[[天文學家]]使用[[紅外線]]波長觀察CW 34時，可以看到兩個不同的區域—星雲的一半是明亮的，另一半是黑暗的。明亮的一面是被附近的[[藍超巨星]]照亮的[[氫]]，而黑暗則是另一側新恆星圍繞中心恆星的地方。

刺激RCW 34發光的能量來源是一顆巨大且極熱的恆星船帆座V391，表面溫度高達30,000°C。由於船帆座V391是一顆[[變星]]，會引發劇烈的現象，包括物質殼的丟棄，影響RCW 34星雲的成分和光發射。船帆座V391類型的[[恆星]]燃燒時間不夠長，不足以爆炸成為[[超新星]]。可以預見，中心恆星的爆炸將徹底改變RCW 34星雲。
