This image taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3) shows a beautiful spiral galaxy called NGC 6744. At first glance, it resembles our Milky Way albeit larger, measuring more than 200,000 light-years across compared to a 100,000-light-year diameter for our home galaxy.美国国家航空航天局/欧空局哈勃太空望远镜的宽视场相机3（WFC3）拍摄的这张照片显示了一个美丽的旋涡星系，称为NGC 6744.乍一看，它类似于我们的银河系，虽然体积更大，但相比之下，它超过200,000光年。 我们的家庭银河系直径10万光年。NGC 6744 is similar to our home galaxy in more ways than one. Like the Milky Way, NGC 6744 has a prominent central region packed with old yellow stars. Moving away from the galactic core, one can see parts of the dusty spiral arms painted in shades of pink and blue; while the blue sites are full of young star clusters, the pink ones are regions of active star formation, indicating that the galaxy is still very lively.NGC 6744在很多方面与我们的家庭星系相似。 与银河系一样，NGC 6744有一个突出的中央区域，里面装满了旧的黄色星星。 远离银河核心，人们可以看到粉红色和蓝色阴影的部分尘土飞扬的旋臂; 虽然蓝色的地方充满了年轻的星团，但是粉红色的星团是活跃恒星形成的区域，这表明星系仍然非常活泼。In 2005, a supernova named 2005at (not visible in this image) was discovered within NGC 6744, adding to the argument of this galaxy’s liveliness. SN 2005at is a Type Ic supernova, formed when a massive star collapses on itself and loses its hydrogen envelope.2005年，在NGC 6744中发现了一颗名为2005at的超新星（在此图中不可见），这增加了这个星系活力的论点。 SN 2005at是一种Ic型超新星，当一颗巨大的恒星自身坍缩并失去其氢气包层时形成。
