位于大熊座北部的螺旋星系NGC 2841距离地球仅4600万光年。在2021年11月、12月和2022年1月的32个晴朗的夜晚，拍摄了这张美丽的宇宙岛的全景。它展示了一个醒目的黄色核、星系盘和暗淡的外部区域。尘埃带、小的恒星形成区和年轻的星团嵌在斑驳的、紧密缠绕的旋臂中。相比之下，许多其他的螺旋星系则表现出巨大的旋臂和巨大的恒星形成区域。NGC 2841的直径超过15万光年，甚至比我们的银河系还要大。x射线图像显示，由此产生的风和恒星爆炸产生了热气羽流，延伸到NGC 2841周围的光环中。

A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This deep view of the gorgeous island universe was captured during 32 clear nights in November, December 2021 and January 2022. It shows off a striking yellow nucleus, galactic disk, and faint outer regions. Dust lanes, small star-forming regions, and young star clusters are embedded in the patchy, tightly wound spiral arms. In contrast, many other spirals exhibit grand, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, even larger than our own Milky Way. X-ray images suggest that resulting winds and stellar explosions create plumes of hot gas extending into a halo around NGC 2841.
