NASA-黎明前总是最黑暗的。这张来自我们的詹姆斯·韦伯太空望远镜的图像显示了N79，一颗巨大的恒星形成区域

案例简介：黎明前总是最黑暗的。这张来自我们的詹姆斯·韦伯太空望远镜的图像显示了N79，这是大麦哲伦星云 (银河系的卫星星系) 内的一个巨大的恒星形成区域。在中红外波长下，韦伯揭示了云层深处的发光气体和尘埃，以及嵌入的婴儿恒星。N79以惊人的速度产生恒星，比我们自己银河系中发现的恒星形成区域快得多。实际上，N79的化学成分与早期宇宙中恒星形成达到顶峰时的化学成分相似。在这里，那些类似于阳光的生动光线实际上是明亮恒星的衍射尖峰。对于明亮、紧凑的物体来说，最引人注目的是，衍射尖峰有点像望远镜的 “签名”。八点图案是望远镜的六边形反射镜设计的结果，结合了它的次级反射镜支柱。同时，我们的哈勃太空望远镜由于其圆形反射镜而产生了四点衍射尖峰图案。在 @ NASAWebb的bio链接中了解更多信息!图像描述: 位于左上象限的一颗明亮的年轻恒星在深色背景上穿过一层层纤细的白色和蓝色云层。星星被厚厚的橙色尖峰包围，呈八点形，覆盖在框架的大部分区域。图像的右上角区域会出现一片黄绿色的云。在云层中还有其他几个亮点，如发光的黄色点，还有另一颗明亮的恒星，右下角有较小的蓝色衍射尖峰。信用: ESA/Webb，NASA和CSA，O。Nayak, M.Meixner # NASA # NASAWebb # JWST # 太空 # 天文学 # 天体摄影 # 星星 # 宇宙 # 望远镜

案例简介：It’s always darkest before the dawn. This image from our James Webb Space Telescope shows N79, a massive star-forming region within the Large Magellanic Cloud (a satellite galaxy of the Milky Way). At mid-infrared wavelengths, Webb reveals glowing gas and dust deep within the clouds, as well as embedded baby stars.N79 produces stars at a furious rate, much faster than star-forming regions found in our own galaxy. In fact, N79’s chemical composition is similar to those from the early universe, when star formation was at its peak.Here, those vivid rays resembling sunlight are actually diffraction spikes for a bright star. Most noticeable for bright, compact objects, diffraction spikes are somewhat like a telescope’s “signature.” The eight-point pattern is the result of the telescope’s hexagonal mirror design, combined with its secondary mirror struts. Meanwhile, our Hubble Space Telescope produces a four-pointed diffraction spike pattern due to its circular mirror.Learn more at @NASAWebb’s link in bio!Image description: A bright young star, located in the upper left quadrant, shines through layers of wispy white and blue clouds on a dark background. The star is surrounded by thick orange spikes in an eight-pointed pattern, overlaid across the majority of the frame. A patch of greenish-yellow clouds appears in the top right area of the image. There are a couple other bright spots seen as glowing yellow dots among the clouds, as well as another bright star with smaller blue diffraction spikes in the bottom right corner.
