在遙遠的星空中，有一個名叫NGC 1566的漩渦星系。它約有四千萬光年遠，位於一個叫做海豚座的星座裡。這個星系看上去就像一朵美麗的花，擁有兩條優雅的螺旋臂。這些螺旋臂上閃爍著明亮的藍色星團，並點綴著紅色的氣體雲和黑色的宇宙塵埃。天文學家用哈勃太空望遠鏡拍攝了很多NGC 1566的照片，來研究那裡的星星是如何形成的，以及超新星是如何爆炸的。在這個星系的中心，有一個強大的黑洞，正在影響周圍的星星和氣體，這讓NGC 1566成為最近和最亮的塞弗特星系之一。

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, red emission nebulas, 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. 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.
