在这张由宇航员唐·佩蒂特拍摄的太空时代照片中，我们银河系的平面延伸到了地球的边缘之外。1月29日，他的相机被对准了与国际空间站对接的“龙”号载人飞船的窗户。这个轨道前哨站当时位于太平洋上空约400公里的高度。运动模糊了下面的地球，而从近地轨道上看到的美丽景象包括银河系突出的卫星星系，即大麦哲伦云和小麦哲伦云，靠近画面的左上角。喜欢南方天空的人也可以看到南十字星座。著名的南星座Crux的四颗最亮的恒星位于图片中心附近，就在明亮的地平线边缘之外，在地球的橙色大气中闪耀。

The plane of our Milky Way galaxy extends beyond the limb of planet Earth in this space age exposure captured by astronaut Don Pettit. His camera, with low light and long duration settings, was pointed out the window of a Dragon crew spacecraft docked with the International Space Station on January 29. The orbital outpost was at an altitude of about 400 kilometers above the Pacific Ocean at the time. Motion blurs the Earth below, while the gorgeous view from low Earth orbit includes the Milky Way's prominent satellite galaxies, known as the Large and Small Magellanic Clouds, near the upper left in the frame. Fans of southern skies can also spot the Southern Cross. The four brightest stars of the famous southern constellation Crux are near picture center, just beyond the edge of the bright horizon and shining through Earth's orange tinted atmospheric glow.
