在船底座星雲的核心
In the Core of the Carina Nebula

船底座星雲的核心發生了什麼? 恆星正在形成、消亡,並留下了令人印象深刻的暗色塵埃細絲。 整個船底座星雲被命名為 NGC 3372 ,橫跨 300 多光年,位於大約 8500 光年外的船底座上。星雲主要由氫氣組成,在這幅高度精細的特寫圖片中,我們可以看到星雲的中心部分發出普遍的紅色和橙色光芒。 邊緣的藍色光暈主要是由微量的發光氧氣產生的。位於星雲中心的年輕大質量恆星在超新星爆炸時會排出塵埃。 海山二(Eta Carinae)是星雲中心能量最強的恆星,在 19 世紀 30 年代曾是天空中最亮的恆星之一,但後來急劇暗淡下來。 你的天空驚喜 1995 年後
原文:What's happening in the core of the Carina Nebula? Stars are forming, dying, and leaving an impressive tapestry of dark dusty filaments. The entire Carina Nebula, cataloged as NGC 3372, spans over 300 light years and lies about 8,500 light-years away in the constellation of Carina. The nebula is composed predominantly of hydrogen gas, which emits the pervasive red and orange glows seen mostly in the center of this highly detailed featured image. The blue glow around the edges is created primarily by a trace amount of glowing oxygen. Young and massive stars located in the nebula's center expel dust when they explode in supernovas. Eta Carinae, the most energetic star in the nebula's center, was one of the brightest stars in the sky in the 1830s, but then faded dramatically.
