编号为NGC 206的大型恒星协会坐落在邻近的仙女座星系的尘埃臂中，以及星系的粉红色恒星形成区。这个螺旋星系也被称为M31，距离我们只有250万光年。ngc206被发现在仙女座圆盘西南范围的这张清晰而详细的特写的中心。ngc206明亮的蓝色恒星表明它很年轻。事实上，它最年轻的大质量恒星的年龄还不到1000万年。ngc206的跨度约为4000光年，比我们银河系盘内由年轻恒星组成的开放星系团或星系团要大得多。它的大小与附近螺旋星系M33中的巨型恒星托儿所NGC 604和大麦哲伦星云中的狼蛛星云相当。

The large stellar association cataloged as NGC 206 is nestled within the dusty arms of the neighboring Andromeda galaxy along with the galaxy's pinkish star-forming regions. Also known as M31, the spiral galaxy is a mere 2.5 million light-years away. NGC 206 is found at the center of this sharp and detailed close-up of the southwestern extent of Andromeda's disk. The bright, blue stars of NGC 206 indicate its youth. In fact, its youngest massive stars are less than 10 million years old. Much larger than the open or galactic clusters of young stars in the disk of our Milky Way galaxy, NGC 206 spans about 4,000 light-years. That's comparable in size to the giant stellar nurseries NGC 604 in nearby spiral M33 and the Tarantula Nebula in the Large Magellanic Cloud.
