在遙遠的宇宙中，有兩個非常特別的星系，分別叫做NGC 1300和NGC 1297。它們就像宇宙中的小島，漂浮在南方的星座——艾瑞丹努斯（Eridanus）上。這兩個星系距離我們有七千萬光年那麼遠，它們是艾瑞丹努斯星系團的一部分。NGC 1300是一個像旋轉的螺旋一樣的星系，大小大約有十萬光年，畫面中可以看到它面對著我們，有著明顯的中央條和非常美麗的螺旋臂。就像我們的銀河系一樣，NGC 1300中也可能藏著一個非常巨大的黑洞。而另一個NGC 1297則是一個近乎圓形的大橢圓星系，位於畫面的上方。這種星系裡的星星大多是年紀較大的，並且不太會形成新的星星，因為它們經過很多次的碰撞和合併，所以看起來會有點不同哦！
原文:
Spiral NGC 1300 and elliptical NGC 1297 are galaxies that lie on the banks of the southern constellation Eridanus (The River). At 70 million light-years distant or more, both are members of the Eridanus Galaxy Cluster. About 100,000 light-years across, at lower left in this sharp, galaxy group photo NGC 1300 is seen face-on with a prominent central bar and grand, sweeping spiral arms. Like other spiral galaxies, including our own barred spiral Milky Way Galaxy, NGC 1300 is thought to have a supermassive central black hole. A contrast in appearance and slightly more distant, NGC 1297 is the roughly spherical large elliptical galaxy near the top of the frame. With little active star formation, elliptical galaxies are composed of older populations of stars and are likely he result of multiple collisions and mergers with spirals.
