韦伯发现了星暴
The James Webb Space Telescope observed “starburst” galaxy NGC 4449, seen in this image released on May 29, 2024. Starbursts are intense periods of star formation usually concentrated at a galaxy’s core, but NGC 4449’s activity is much more widespread — likely due to past interactions with its galactic neighbors. Astronomers can study this galaxy to look into the past: NGC 4449 is similar to early star-forming galaxies, which also grew by merging with other systems.

詹姆斯·韦伯太空望远镜在2024年5月29日发布的这张照片中观测到了“星爆”星系NGC 4449。恒星爆发是恒星形成的密集时期，通常集中在星系的核心，但NGC 4449的活动范围要广得多，这可能是由于过去与近邻星系的相互作用。天文学家可以研究这个星系来回顾过去：NGC 4449与早期恒星形成的星系相似，这些星系也通过与其他系统合并而成长。
