这只是空山上的一棵孤独的树吗？也许这是开始，但放眼未来。在那里，一个忙碌的宇宙可能等待着被发现。首先，在物理上，在树的左边，是火星。这颗红色星球是美国国家航空航天局“毅力号”探测器的新家，本月日落时，它在西方地平线上仍然可见。在这棵树的右边是昴宿星团，一个由几颗明亮的蓝色恒星组成的明亮星团。这张特色照片是上个月初在加拿大新斯科舍省米尔福德醋山同一地点拍摄的几张独立的前景和背景照片的合成图。那时，火星一个晚上接一个晚上慢慢地经过，几乎就在遥远的七姐妹星团的前面。下一次火星从角度接近昴宿星团的时间将是2038年。

Is this just a lonely tree on an empty hill? To start, perhaps, but look beyond. There, a busy universe may wait to be discovered. First, physically, to the left of the tree, is the planet Mars. The red planet, which is the new home to NASA's Perseverance rover, remains visible this month at sunset above the western horizon. To the tree's right is the Pleiades, a bright cluster of stars dominated by several bright blue stars. The featured picture is a composite of several separate foreground and background images taken within a few hours of each other, early last month, from the same location on Vinegar Hill in Milford, Nova Scotia, Canada. At that time, Mars was passing slowly, night after night, nearly in front of the distant Seven Sisters star cluster. The next time Mars will pass angularly as close to the Pleiades as it did in March will be in 2038.
