说明: 天空中的北美洲星云，能做到地球上的北美洲无法做到的事 -- 形成恒星。具体而言，形似地球的中美洲和墨西哥的明亮天鹅座墙，其实是气体、尘埃和新诞生恒星的複合体。这幅主题影像显示，这道恒星诞生之墙正受到年轻亮星的照亮和侵蚀，而这些新恒星所製造的黝黑尘埃也遮掩了部分的墙体。影像所呈现的部分北美洲星云 （NGC 7000），宽约15光年，位于天鹅星座方向约1,500光年远之处。

Explanation: The North America nebula on the sky can do what theNorth America continent on Earth cannot -- form stars. Specifically, in analogy to the Earth-confined continent, the bright part that appears as Central America and Mexico is actually a hot bed of gas, dust, and newly formed stars known as the Cygnus Wall. The featured image shows the star forming wall lit and eroded by bright young stars, and partly hidden by the dark dust they have created. The part of the North America nebula (NGC 7000) shown spans about 15 light years and lies about 1,500 light years away toward the constellationof the Swan (Cygnus).
