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.

说明: 这幅以明亮发射星云为主题的望远镜影像，远眺银河盘面上满布星云的天鹅座。这团常称为郁金香星云的明亮气体与尘埃云，也是天文学家夏普勒斯在1959年发表的星表里，编录号为Sh2-101的天体。这朵距离约8,000光年，宽约70光年的美丽“花朵”，绽放在这幅组合影像的中心附近。位在天鹅座OB3星协边缘的年轻活跃O型星，发出的紫外辐射电离并驱动郁金香星云发光。
