银河系在无线电波中是什么样子的？为了更好地找到答案，GLEAM用澳大利亚默奇森广域阵列拍摄的高分辨率射电光对我们银河系的中央波段进行了调查。随着特色视频缓慢滚动，左侧可见射电光（71 - 231 MHz），右侧可见来自同一视场的可见光。差异如此之大，是因为大多数物体在射电和可见光下的发光不同，而且可见光被附近的星际尘埃阻挡。这些差异在朝向银河系中心的方向上尤其明显，大约在三分之一的地方可以看到。在射电中出现的许多特征中，明亮的红色斑块通常是爆炸恒星的超新星遗迹，而蓝色区域是充满明亮年轻恒星的恒星托儿所。你知道吗？ APOD可以在许多网站上找到，包括社交媒体。

What does the Milky Way look like in radio waves? To better find out, GLEAM surveyed the central band of our galaxy in high resolution radio light as imaged by the Murchison Widefield Array in Australia. As the featured video slowly scrolls, radio light (71 - 231 MHz) is seen on the left and visible light -- from the same field -- on the right. Differences are so great because most objects glow differently in radio and visible light, and because visible light is stopped by nearby interstellar dust. These differences are particularly apparent in the direction toward the center of our galaxy, seen about a third of the way through. Among the many features that appear in the radio, bright red patches are usually supernova remnants of exploded stars, while areas colored blue are stellar nurseries filled with bright young stars.
