Star Cluster Dreams

Explanation: Located some 7,000 light-years away toward the constellation Perseus，this pair of open or galactic star clusters really is visible to the unaided eye and was cataloged in 130 BC by Greek astronomer Hipparchus. Now known as h and chi Persei (NGC 869/884), the clusters themselves are separated by a few hundred light-years and contain stars much younger, and hotter than the Sun. But what if this famous double star cluster were closer, say only 700 light-years distant from our fair solar system, crowding our sky with stars? Astrophotographer Jose Suro also imagines a clear, moonless, dark night sky on a warm evening near tranquil waters. The foreground is illuminated by starlight in his composited dreamlike image of the cluster pair. He notes that while the solar system is not in the vicinity of such rich clusters of stars, dark night skies and warm evenings can still be inspiring on planet Earth.

梦幻般的恒星团

解释：位于7000光年之外的英仙座, 我们肉眼能看到这两个极大的疏散星团，早在公元前130年就被希腊天文学家希帕库斯分类了。现在被称为英仙座双星团  (NGC 869/884)，它们相隔数百光年而且包含的恒星都比太阳要更年轻，更明亮。但若这个著名双星团是离我们非常接近的，例如离我们的太阳系只有700光年远，我们的天空会多很多星星吗？在暖和的夜晚下，平静的湖畔，天文摄影师约什.索罗同样拍摄到了清晰，无月光的夜空。在他那合成的梦想图片中前景被双星团的星光照亮了。他解释虽然在太阳系附近是不会有这种富含恒星的星团，但黑暗的夜空和温暖的晚上在地球这行星上仍然是宁人激动的。
