Point Reyes Milky Way

Explanation: Northern winter constellations and a long arc of the Milky Way are setting in this night skyscape looking toward the Pacific Ocean from Point Reyes on planet Earth’s California coast. Sirius, alpha star of Canis Major, is prominent below the starry arc toward the left. Orion’s yellowish Betelgeuse, Aldebaran in Taurus, and the blue tinted Pleiades star cluster also find themselves between Milky Way and northwestern horizon near the center of the scene. The nebulae visible in the series of exposures used to construct this panoramic view were captured in early March, but are just too faint to be seen with the unaided eye. On that northern night their expansive glow includes the reddish semi-circle of Barnard’s Loop in Orion and NGC 1499 above and right of the Pleiades, also known as the California Nebula.

说明: 在这片从地球加州海岸的雷耶斯角看向太平洋的夜空景观中,北天冬季星座和银河系的长长盘弧落向太平洋。大犬座最明亮的天狼星,是在银河恒星拱下方很吸睛的天体。猎户座泛黄的参宿四金牛座的毕宿五及泛蓝的昴宿星团,也出现在银河及西北地平线之间,靠近影像的中心附近。用于构建这张全景图的多张照星云照片,则是在今年3月初所拍摄的;这些星云都是极为昏暗,肉眼不得见的天体。在那个北半球的夜晚, 出现在天空中、幅员广阔的辉光天体,还包括猎户座里半圆形的泛红巴纳德环、以及昴宿星团右上方、亦称为加州星云的NGC 1499。
