在这张深邃的夜空中，银河系的核心正从智利山顶的拉西拉天文台升起。欧洲南方天文台的新技术望远镜向人马座的方向看去，我们的星系中心在左边的侧翼，它率先使用主动光学技术来精确控制大型望远镜反射镜的形状。右边是ESO的3.6米望远镜，它是搜寻系外行星的HARPS和NIRPS光谱仪的所在地。在它们之间，星系的中央凸起充满了星际尘埃云、明亮的恒星、星团和星云。从形成恒星的泻湖星云M8发出的突出的红色氢辐射靠近中心。三裂星云，M20，结合了尘埃反射星云的蓝光和宇宙泻湖左侧的红色辐射。这两个星系都是用望远镜游览银河系中心的热门站点。这张合成图像是2023年4月拍摄的地面和天空的单独曝光叠加，所有这些都是用相同的取景和相机设备连续拍摄的。

The core of the Milky Way is rising beyond the Chilean mountain-top La Silla Observatory in this deep night skyscape. Seen toward the constellation Sagittarius, our home galaxy's center is flanked on the left, by the European Southern Observatory's New Technology Telescope which pioneered the use of active optics to accurately control the shape of large telescope mirrors. To the right stands the ESO 3.6-meter Telescope, home of the exoplanet hunting HARPS and NIRPS spectrographs. Between them, the galaxy's central bulge is filled with obscuring clouds of interstellar dust, bright stars, clusters, and nebulae. Prominent reddish hydrogen emission from the star-forming Lagoon Nebula, M8, is near center. The Trifid Nebula, M20, combines blue light of a dusty reflection nebula with reddish emission just left of the cosmic Lagoon. Both are popular stops on telescopic tours of the galactic center. The composited image is a stack of separate exposures for ground and sky made in April 2023, all captured consecutively with the same framing and camera equipment.
