这个星系发生了一些奇怪的事情，但是是什么呢？被称为雪茄星系，编号为M82，红色的发光气体和尘埃正从中心被抛出。虽然这个星暴星系肯定是最近经过它的邻居，大型螺旋星系M81时激起的，但这并不能完全解释向外膨胀的红色气体和尘埃的来源。有证据表明，这些物质是由许多恒星形成的粒子风共同吹出的，共同形成了银河系的超级风。在这些特色图像中，左边是哈勃太空望远镜在可见光下拍摄的图像，而右边是詹姆斯韦伯太空望远镜在红外光下拍摄的中心区域图像。对新的韦伯图像的详细检查显示，意想不到的是，这些红色发光的尘埃与热等离子体有关。对这个奇怪的附近星系性质的研究肯定会继续下去。日全食图像：值得注意的提交给APOD

Something strange happened to this galaxy, but what? Known as the Cigar Galaxy and cataloged as M82, red glowing gas and dust are being cast out from the center. Although this starburst galaxy was surely stirred up by a recent pass near its neighbor, large spiral galaxy M81, this doesn't fully explain the source of the red-glowing outwardly expanding gas and dust. Evidence indicates that this material is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. In the featured images, a Hubble Space Telescope image in visible light is shown on the left, while a James Webb Space Telescope image of the central region in infrared light is shown on the right. Detailed inspection of the new Webb image shows, unexpectedly, that this red-glowing dust is associated with hot plasma. Research into the nature of this strange nearby galaxy will surely continue.
