从地球看昴宿星团

说明: 昴宿星团（M45）在地球的夜空中闪耀，这群紧密的恒星，距离地球约400光年，位于金牛座和本银河系猎户臂方向。自古以来，这片非凡的天体群就已被人们所熟知，肉眼可见。昴宿星团在北半球和南半球都适合观赏，几个世纪以来，它与许多文化传统和庆典紧密关连，其中包括跨季节庆的万圣节。在希腊神话中，昴宿星团是天文巨人阿特拉斯和海仙女普勒俄涅的七个女儿。伽利略首次用望远镜观察并绘制了这个星团，其中包含肉眼看不见的微弱星星，而查尔斯·梅西耶将这个星团的位置记录于他著名的非彗星天体目录中，编号为第45位。在这幅来自地球的壮丽夜空景观中，昴宿星团的群星仿佛镶嵌在尘埃弥漫的蓝色反射星云之中，高悬于纽西兰最高峰之一的塞夫顿山之上。这片星团在当地被称为玛塔里基（Matariki），与毛利新年庆典息息相关。

英文原文:
Explanation: The lovely Pleiades star cluster shines in Earth’s night sky, a compact group of stars some 400 light-years distant toward the constellation Taurus and the Orion Arm of our Milky Way galaxy . Recognized since ancient times, the remarkable celestial gathering is visible to the unaided eye. The Pleiades cluster is also well-placed for viewing from both northern and southern hemispheres, and over the centuries has become connected to many cultural traditions and celebrations, including the cross-quarter day celebration Halloween . In Greek myth , the Pleiades were seven daughters of the astronomical titan Atlas and sea-nymph Pleione. Galileo first sketched the star cluster viewed through his telescope with stars too faint to be seen by eye and Charles Messier recorded the position of the cluster as the 45th entry in his well-known catalog of things which are not comets. In this dramatic night skyscape from planet Earth, the stars of the Pleiades appear embedded in dusty blue reflection nebulae, poised above Mt Sefton, one of the tallest peaks in New Zealand. There known as Matariki , the star cluster is associated with the celebration of the Maori new year.
