如果不完美，那么这个螺旋星系至少是最上镜的星系之一。NGC 1566是一个包含数十亿颗恒星的宇宙岛屿，距离海豚座（多拉多）约4000万光年，呈现出一幅华丽的正面景象。NGC 1566被归类为一个宏伟的设计螺旋，它展示了两个突出而优雅的旋臂，明亮的蓝色星团和黑暗的宇宙尘埃带描绘了它们。哈勃太空望远镜拍摄了大量NGC 1566的图像，用于研究恒星形成、超新星和螺旋星系异常活跃的中心。其中一些图像被免费下载、组合，并由一个勤奋的业余爱好者进行数字处理，形成了这幅特色图像。NGC 1566的耀斑中心使这个螺旋星系成为离我们最近、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，对周围的恒星和气体造成严重破坏。几乎超空间：随机APOD生成器

If not perfect, then this spiral galaxy is at least one of the most photogenic. An island universe containing billions of stars and situated about 40 million light-years away toward the constellation of the Dolphinfish (Dorado), NGC 1566 presents a gorgeous face-on view. Classified as a grand design spiral, NGC 1566 shows two prominent and graceful spiral arms that are traced by bright blue star clusters and dark cosmic dust lanes. Numerous Hubble Space Telescope images of NGC 1566 have been taken to study star formation, supernovas, and the spiral's unusually active center. Some of these images, stored online in the Hubble Legacy Archive, were freely downloaded, combined, and digitally processed by an industrious amateur to create the featured image. NGC 1566's flaring center makes the spiral one of the closest and brightest Seyfert galaxies, likely housing a central supermassive black hole wreaking havoc on surrounding stars and gas.
