As seen in a picture released in August by scientists with the NASA/ESA Hubble Space Telescope, one of galaxy NGC 2146's arms is bent at a 45-degree angle, such that the dense limb has looped in front of the galaxy's core, as seen from Earth. |
在科学家于8月份发布的一张图片中可以看到,星系NGC 2146的一条旋臂呈45度角发生弯曲,这样在地球上看去,这条高密度旋臂在该星系中心前方呈现出环状。图片是由NASA/ESA的哈勃天空望远镜拍摄的。 |
The most likely explanation is that the gravity of an unidentified nearby galaxy is disturbing NGC 2146's arm, causing the galaxy to warp. |
对此可能性最大的解释是,附近有一个未被发现的星系,其引力正在干扰NGC 2146的这条旋臂,致使该星系发生扭曲。 |
