Explanation: Framing a bright emission region, this telescopic view looks out across a pretty field of stars along the plane of our Milky Way Galaxy, toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the reddish glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms near the center of this composite image. Ultraviolet radiation from young energetic O stars at the edge of the Cygnus OB3 association, ionizes the atoms and powers the emission from the Tulip Nebula.

天鹅座内的郁金香星云

这幅照片是由望远镜拍摄的，它沿着银道面的星场，以位于天鹅座方向的明亮发射星云为主题。这个被民间天文爱好者称为郁金香星云的红色发光气体云，在天文学家沙普利斯编制的1959星表里编号为Sh2-101。距离地球约8000光年，宽度约70光年，这个复杂而美丽的星云位于图像的中心。位于天鹅座OB3区域边缘的，年轻高能的O型恒星的紫外辐射为郁金香星云的辐射提供了能量。
