The brilliant tapestry of young stars flaring to life resembles a glittering fireworks display in this Hubble Space Telescope image. The sparkling centerpiece of this fireworks show is a giant cluster of thousands of stars called Westerlund 2. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina. Hubble’s Wide Field Camera 3 pierced through the dusty veil shrouding the stellar nursery in near-infrared light, giving astronomers a clear view of the nebula and the dense concentration of stars in the central cluster. The cluster measures between six light-years and 13 light-years across.

在这张哈勃太空望远镜拍摄的照片中,闪耀着生命的年轻恒星组成的绚丽多彩的织锦就像一个闪闪发光的烟花表演。这场烟花表演的中心是一个由数千颗星星组成的巨星团,名为韦斯特伦德2号。这个星团位于一个被称为Gum 29的恒星繁殖地,距离地球2万光年,位于船底座哈勃望远镜的广角相机3号在近红外光的照射下,穿透了覆盖在恒星摇篮上的灰尘,让天文学家清楚地看到了星云和中央星团中密集的恒星。星系团的长度在6光年到13光年之间。
