这些黑暗的柱子可能看起来具有破坏性，但它们正在创造恒星。这张鹰状星云的柱状图像结合了哈勃太空望远镜拍摄的可见光和詹姆斯韦伯太空望远镜拍摄的红外图像，突出了从分子氢气和尘埃柱中出现的蒸发气体球体（EGGs）。这些巨大的柱子有光年长，密度很大，内部气体在引力作用下收缩形成恒星。在每根柱子的末端，明亮的年轻恒星的强烈辐射会导致低密度物质蒸发，留下由密集EGGs组成的恒星托儿所。与疏散星团M16有关的鹰状星云位于7000光年之外。拼图挑战：当天的天文学难题

These dark pillars may look destructive, but they are creating stars. This pillar-capturing picture of the Eagle Nebula combines visible light exposures taken with the Hubble Space Telescope with infrared images taken with the James Webb Space Telescope to highlight evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust. The giant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars. At each pillar's end, the intense radiation of bright young stars causes low density material to boil away, leaving stellar nurseries of dense EGGs exposed. The Eagle Nebula, associated with the open star cluster M16, lies about 7000 light years away. Jigsaw Challenge: Astronomy Puzzle of the Day
