NGC 3572附近的恒星、尘埃和气体

说明:恒星的形成可以是丰富多彩的。这幅彩色的宇宙肖像在NGC 3572最近形成的恒星附近发出了炽热的气体和黑暗的尘埃，这是一个在Carina星云附近研究得很少的星团。来自NGC 3572的恒星在图像底部附近可见，而上面的膨胀气体云可能是其形成星云的残留物。这幅图像的鲜明色调是由氢、氧和硫释放出的特定颜色并将它们与通过红色，绿色和蓝色的宽带滤光片记录的图像混合而创建的。NGC 3572附近的这个星云横跨大约100光年，距离船底星座(船底座)约9000光年。在几百万年内，图中所示的气体可能会消散，而引力碰撞可能会在大约10亿年的时间里驱散星团中的恒星。

Stars, Dust, and Gas near NGC 3572

Explanation: Star formation can be colorful. This chromatic cosmic portrait features glowing gas and dark dust near some recently formed stars of NGC 3572, a little-studied star cluster near the Carina Nebula. Stars from NGC 3572 are visible near the bottom of the image, while the expansive gas cloud above is likely what remains of their formation nebula. The image’s striking hues were created by featuring specific colors emitted by hydrogen, oxygen, and sulfur, and blending them with images recorded through broadband filters in red, green, and blue. This nebula near NGC 3572 spans about 100 light years and lies about 9,000 light years away toward the southern constellation of the Ship’s Keel (Carina). Within a few million years the pictured gas will likely disperse, while gravitational encounters will likely disperse the cluster stars over about a billion years.
