韦伯在船底星云中发现了年轻恒星的爆发
By taking a closer look at one of Webb’s first images, the iconic Cosmic Cliffs, scientists have found dozens of energetic jets and outflows from young stars previously hidden by dust clouds. The discovery marks the beginning of a new era of investigating how stars like our Sun form, and how the radiation from nearby massive stars might affect the development of planets.
The two dozen previously unknown outflows from extremely young stars were found by analyzing data from a specific wavelength of infrared light (4.7 microns). Webb’s observations uncovered a gallery of objects ranging from small fountains to burbling behemoths that extend light-years from the forming stars.

通过仔细观察韦伯的第一张照片之一，标志性的宇宙悬崖，科学家们发现了数十个来自年轻恒星的高能喷流和外流，这些恒星以前被尘云所掩盖。这一发现标志着一个新时代的开始，即研究像太阳这样的恒星是如何形成，以及附近大质量恒星的辐射如何影响行星的发展。
通过分析特定波长的红外光（波长为4.7微米）的数据，天文学家发现了20多个以前未知的氢分子所揭示的极年轻恒星的外流。韦伯的观测发现了一系列物体，从小型喷泉到汩汩作响的庞然大物，它们距离形成的恒星有光年之遥。
