NGC 1566是一个由数十亿颗恒星组成的宇宙孤岛，距离我们大约6000万光年，位于南部的多拉多星座。它通常被称为西班牙舞者星系，从我们银河系的角度来看，它是正面的。这是一个华丽的宏伟设计螺旋，这个星系的两个优雅的旋臂跨度超过10万光年，由明亮的蓝色星团，粉红色的恒星形成区和旋转的宇宙尘埃带所描绘。NGC 1566的耀斑中心使其成为离我们最近、最明亮的塞弗特星系之一。它的中心可能有一个超大质量黑洞，对周围的恒星、气体和尘埃造成了严重破坏。在这幅清晰的南部星系肖像中，这些尖尖的恒星位于银河系内部。

An island universe of billions of stars, NGC 1566 lies about 60 million light-years away in the southern constellation Dorado. Popularly known as the Spanish Dancer galaxy, it's seen face-on from our Milky Way perspective. A gorgeous grand design spiral, this galaxy's two graceful spiral arms span over 100,000 light-years, traced by bright blue star clusters, pinkish starforming regions, and swirling cosmic dust lanes. NGC 1566's flaring center makes the spiral one of the closest and brightest Seyfert galaxies. It likely houses a central supermassive black hole wreaking havoc on surrounding stars, gas, and dust. In this sharp southern galaxy portrait, the spiky stars lie well within the Milky Way.
