詹姆斯韦伯太空望远镜拍摄了NGC 2392星云的新红外图像，这一星云因其独特的狮子脸形状而被称为"狮子星云"1。图像揭示了一颗白矮星及其周围气体和尘埃的详细结构1。该白矮星是一颗垂死的类日恒星残骸，其释放的强烈辐射正在雕刻周围区域，而幸存的尘埃团簇形成了狮子的"鬃毛"1。
这一观测利用了詹姆斯韦伯的近红外相机（NIRCam）和中红外仪器（MIRI）进行1。星云中的气体和尘埃已经演化了数千年1。根据天文学家的估计，这一宇宙结构还需约10,000年才会最终消散1。
The James Webb Space Telescope has captured detailed infrared images of NGC 2392, a nebula whose distinctive lion-like appearance is being sculpted by a dying star at its core 1. The observations, conducted on August 12, 2026, using the telescope's Near Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), reveal the intricate structure of gas and dust surrounding an extremely hot white dwarf—the remnant left behind by a sun-like star 1.
At the center of this cosmic landscape lies the white dwarf, which emits intense radiation that is actively carving the surrounding nebula into its characteristic feline shape 1. The surviving dust clusters encircling the stellar remnant form what astronomers describe as the lion's "mane" 1. After evolving over thousands of years, the nebula is expected to take approximately 10,000 more years before it completely disperses 1. The James Webb Space Telescope is an international collaborative project of NASA, the European Space Agency, and the Canadian Space Agency 1.
