星星正在摧毁柱子。更具体地说，图像中心的一些新形成的恒星发出的光能量如此之大，以至于蒸发了周围柱中的气体和尘埃。与此同时，这些柱子本身仍在努力形成新的恒星。整个背景是星团ngc602，这张新的远景是由韦伯太空望远镜用多种红外颜色拍摄的。相比之下，一张由哈勃太空望远镜拍摄的相同星团在可见光下的翻转图像。ngc602位于小麦哲伦星云（SMC）的边缘附近，小麦哲伦星云是我们银河系的一个小卫星星系。在SMC的估计距离上，这张特色图片的跨度约为200光年。在至少数亿光年之外，还可以看到各种诱人的背景星系——大多在边缘附近。

The stars are destroying the pillars. More specifically, some of the newly formed stars in the image center are emitting light so energetic that is evaporating the gas and dust in the surrounding pillars. Simultaneously, the pillars themselves are still trying to form new stars. The whole setting is the star cluster NGC 602, and this new vista was taken by the Webb Space Telescope in multiple infrared colors. In comparison, a roll-over image shows the same star cluster in visible light, taken previously by the Hubble Space Telescope. NGC 602 is located near the perimeter of the Small Magellanic Cloud (SMC), a small satellite galaxy of our Milky Way galaxy. At the estimated distance of the SMC, the featured picture spans about 200 light-years. A tantalizing assortment of background galaxies are also visible -- mostly around the edges -- that are at least hundreds of millions of light-years beyond.
