云彩看起来像一只牡蛎，星星看起来像珍珠，但要放眼望去。在距离我们大约20万光年远的卫星星系小麦哲伦星云的边缘，坐落着500万年的年轻星团ngc602。在这张令人惊叹的哈勃图像中，ngc602被出生的气体和尘埃包围着。奇异的山脊和向后扫的形状强烈表明，NGC 602的大质量年轻恒星发出的高能辐射和冲击波侵蚀了尘埃物质，并引发了恒星形成的进程，使其远离星团中心。在小麦哲伦星云的估计距离上，这张特色图片的跨度约为200光年，但在这张清晰的多色视图中，还可以看到各种诱人的背景星系。背景星系距离NGC 602数亿光年或更远。

The clouds may look like an oyster, and the stars like pearls, but look beyond. Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this stunning Hubble image of the region. Fantastic ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602's massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster's center. At the estimated distance of the Small Magellanic Cloud, the featured picture spans about 200 light-years, but a tantalizing assortment of background galaxies are also visible in this sharp multi-colored view. The background galaxies are hundreds of millions of light-years or more beyond NGC 602.
