银河系中心附近发生了什么？为了帮助找到答案，一幅新的详细全景图已经完成，它在射电和x射线光下探索了银河平面上方和下方的区域。钱德拉轨道天文台拍摄的x射线光显示为橙色（热），绿色（热）和紫色（最热），并与MeerKAT阵列获得的无线电波中非常详细的图像（灰色）叠加在一起。交互是大量和复杂的。不断膨胀的超新星残骸、新形成的恒星产生的热风、异常强烈的碰撞磁场以及中心的超大质量黑洞等银河系野兽都在这个直径只有1000光年的空间里相互争斗。薄而明亮的条纹似乎是由碰撞区域的磁场扭曲和新连接造成的，创造了一种能量充沛的银河系内部空间天气，与我们的太阳创造的天气相似。持续的观测和研究不仅能让我们更清楚地了解我们自己星系的历史和演化，还能让我们了解所有星系。

What's going on near the center of our galaxy? To help find out, a newly detailed panorama has been composed that explores regions just above and below the galactic plane in radio and X-ray light. X-ray light taken by the orbiting Chandra Observatory is shown in orange (hot), green (hotter), and purple (hottest) and superposed with a highly detailed image in radio waves, shown in gray, acquired by the MeerKAT array. Interactions are numerous and complex. Galactic beasts such as expanding supernova remnants, hot winds from newly formed stars, unusually strong and colliding magnetic fields, and a central supermassive black hole are all battling in a space only 1000 light years across. Thin bright stripes appear to result from twisting and newly connecting magnetic fields in colliding regions, creating an energetic type of inner galactic space weather with similarities to that created by our Sun. Continued observations and study hold promise to not only shed more light on the history and evolution of our own galaxy -- but all galaxies.
