Stars, Gas, and Dust Battle in the Carina Nebula 
Image Credit & Copyright: Bastien Foucher
Explanation: Chaos reigns in the Carina Nebula where massive stars form and die. Striking and detailed, this close-up of a portion of the famous nebula is a combination of light emitted by hydrogen (shown in red) and oxygen (shown in blue). Dramatic dark dust knots and complex features revealed are sculpted by the winds and radiation of Carina's massive and energetic stars. One iconic feature of the Carina Nebula is the dark V-shaped dust lane that occurs in the top half of the image. The Carina Nebula spans about 200 light years, lies about 7,500 light years distant, and is visible with binoculars toward the southern constellation of Carina. In a billion years after the dust settles -- or is destroyed, and the gas dissipates -- or gravitationally condenses, then only the stars will remain -- but not even the brightest ones.

说明: 混沌统治在大星星形成并死亡的卡里纳星云中。醒目而细致 的一部分着名的星云的特写是由氢(红色显示)和氧气(蓝色显示) 发出的光的组合 。戏剧性的黑暗尘埃结 和复杂的特征被 雕刻在Carina的大量和充满活力的星星的风和辐射下 。卡里纳星云的一个标志性特征 是 图像上半部分发生的黑色V形防尘通道。在船底座星云横跨约200 光年,距离我们大约7, 500光年遥远,可见双筒望远镜朝向南部星座的嘉年华。在尘埃沉降或被破坏,气体消散或重力凝结的 十亿年之后 ,只有 星星将保持 - 但是 甚至不是最亮的。
