Out of a sea of silver sparkles from nearby stars, a ripple of bright blue gas threads through this galaxy like a misshapen lake. A keen eye can also spot a few other galaxies that, while masquerading as stars at first glance, reveal their true nature on closer inspection of this image from the Hubble Space Telescope (@NASAHubble). The central galaxy streaked with color was discovered by DeLisle Stewart in 1900 and is located approximately 28 million light-years away. It contains an active galactic nucleus: an extremely luminous central region so alight with radiation that it can outshine the rest of the galaxy put together.
在附近恒星闪闪发光的海洋中，一道明亮的蓝色气体像一个畸形的湖水穿过这个星系。敏锐的眼睛还可以发现其他一些星系，虽然第一眼看上像星星，但通过仔细观察哈勃太空望远镜（@NASAHubble）的这幅图像，可以发现它们的真实本质。 1900年，DeLisle Stewart发现了带有颜色斑点的中央星系，距离大约2800万光年远。它包含一个活跃的银河核心：一个非常明亮的中心区域，因此可以放射线照射，可以将星系的其余部分放在一起。
This galaxy has been imaged by Hubble for several studies of nearby active galaxies. By using Hubble to explore the small-scale structures of active galaxies in nearby galaxies, astronomers can observe the traces of collisions and mergers, central galactic bars, nuclear starbursts, jets or outflows, and other interactions between a galactic nucleus and its surrounding environment. Images such as this can help astronomers understand more about the true nature of the galaxies we see throughout the cosmos.
这个星系已经由哈勃望远镜对附近活动星系的几项研究成像。通过使用哈勃来探索附近星系中活动星系的小尺度结构，天文学家可以观察碰撞和合并，中央星系条，核星爆，射流或流出以及银河核与周围环境之间的其他相互作用。像这样的图像可以帮助天文学家更多地了解我们在整个宇宙中看到的星系的真实性质。
