每天晚上的天空都一样吗？不——夜空每天晚上都在以很多方式变化。为了更好地探索夜空的变化，美国国家科学基金会和美国能源部委托位于智利Cerro Pachón的Vera C. Rubin天文台。在常规操作之前的最后测试中，鲁宾将开始探索这些夜间变化——微小的差异可以告诉我们很多关于我们神奇的宇宙和令人惊讶的物体动物园的信息。鲁宾将利用一面直径超过8米的镜子，每隔几个晚上就会不断地对整个可见天空进行重新成像，以发现新的超新星、潜在危险的小行星、暗淡的彗星和变星，并绘制出可见宇宙的大规模结构。照片中，我们银河系遥远的中央带似乎从新运行的天文台流出。这张上个月拍摄的特色照片是由21张横跨夜空的图像合成而成的，捕捉了地平线上的气辉和左下角的小麦哲伦星云。APOD满30岁了！： 6月11日在安克雷奇举行免费公开讲座

Is the sky the same every night? No -- the night sky changes every night in many ways. To better explore how the night sky changes, the USA's NSF and DOE commissioned the Vera C. Rubin Observatory in Cerro Pachón, Chile. In final testing before routine operations, Rubin will begin to explore these nightly changes -- slight differences that can tell us much about our amazing universe and its surprising zoo of objects. With a mirror over 8 meters across, Rubin will continually reimage the entire visible sky every few nights to discover new supernovas, potentially dangerous asteroids, faint comets, and variable stars -- as well as mapping out the visible universe's large-scale structure. Pictured, the distant central band of our Milky Way Galaxy appears to flow out from the newly operational observatory. Taken last month, the featured picture is a composite of 21 images across the night sky, capturing airglow on the horizon and the Small Magellanic Cloud galaxy on the lower left.
