你能找到玫瑰星云吗？左上角那个巨大的、红色的、花朵般的星云似乎是显而易见的选择，但实际上那只是围绕着锥星云和狐毛星云的漫射氢发射。著名的玫瑰星云实际上位于右下方，通过不规则的细丝与其他星云相连。因为罗塞塔号上的这幅特色图像是如此的宽和深，它似乎包含了其他的花朵。被命名为NGC 2237的玫瑰星云的中心由疏散星团NGC 2244的明亮蓝色恒星组成，它们的风和高能光正在疏散星云的中心。玫瑰星云距离我们大约5000光年远，仅它本身的直径就有满月直径的三倍。这片鲜花盛开的田野可以在独角兽星座的方向找到。

Can you find the Rosette Nebula? The large, red, and flowery-looking nebula on the upper left may seem the obvious choice, but that is actually just diffuse hydrogen emission surrounding the Cone and Fox Fur Nebulas. The famous Rosette Nebula is really located on the lower right and connected to the other nebulas by irregular filaments. Because the featured image of Rosetta's field is so wide and deep, it seems to contain other flowers. Designated NGC 2237, the center of the Rosette nebula is populated by the bright blue stars of open cluster NGC 2244, whose winds and energetic light are evacuating the nebula's center. The Rosette Nebula is about 5,000 light years distant and, just by itself, spans about three times the diameter of a full moon. This flowery field can be found toward the constellation of the Unicorn (Monoceros).
