这个宝箱里装满了星星。这张特色图片是由美国宇航局的詹姆斯·韦伯太空望远镜获得的，它显示了我们银河系内船底座星云中的一根尘埃柱，距离我们大约7500光年。它是由星际气体和尘埃形成的，并受到邻近恒星的强大恒星风和辐射的影响，比如附近的船底座埃塔恒星系统，它的亮度比500万个太阳还要高。柱子内部的恒星形成正在挖掘它的头部，形成了打开的胸部盖子。天文学家估计大约有70颗恒星聚集在一个紧密的星团中。这个星团现在被认为只有大约130万年的历史。它丰富的年轻恒星包括一颗质量约为太阳19倍的大质量恒星。大质量的恒星比小质量的恒星更罕见，更明亮，进化得更快。它们是宝箱中最闪亮的珠宝。APOD的主要NASA网站正在迁移：从APOD .

This treasure chest is full of stars. The featured image was obtained with NASA's James Webb Space Telescope and shows a dust pillar in the Carina Nebula inside our Galaxy, roughly 7500 light-years away. It is formed by interstellar gas and dust, and shaped by powerful stellar winds and radiation form neighboring stars like the nearby Eta Carinae stellar system which is more luminous than 5 million suns. The star formation inside the pillar is excavating its head, creating the open lid of the chest. Astronomers estimate that there are about 70 stars in a compact cluster inside the pillar. This cluster is now thought to be only around 1.3 million years old. Its bounty of young stars includes a massive star approximately 19 times as massive as the Sun. More massive stars are rarer, shine brighter and evolve faster than less massive stars. They are the shiniest jewels in the treasure chest.
