离地球最近的活动星系是哪个？那就是半人马座A，编号为NGC 5128，距离我们只有1200万光年。在两个正常星系的碰撞中形成的半人马座a显示出几个独特的特征，包括穿过其中心的黑暗尘埃带，恒星和气体的外壳，以及从其中心的超大质量黑洞喷射出的粒子射流。在过去的10年里，在新西兰奥克兰，一个自制的望远镜在310小时内拍摄了一系列可见光图像，这幅特色图像捕捉了所有这些图像。半人马座A中心从低能无线电波到高能伽马射线的亮度，使其成为活跃星系的基础。天体物理学家：在天体物理学源代码库中浏览3500多个代码

What's the closest active galaxy to planet Earth? That would be Centaurus A, cataloged as NGC 5128, which is only 12 million light-years distant. Forged in a collision of two otherwise normal galaxies, Centaurus A shows several distinctive features including a dark dust lane across its center, outer shells of stars and gas, and jets of particles shooting out from a supermassive black hole at its center. The featured image captures all of these in a composite series of visible light images totaling over 310 hours captured over the past 10 years with a homebuilt telescope operating in Auckland, New Zealand. The brightness of Cen A's center from low-energy radio waves to high-energy gamma rays underlies its designation as an active galaxy.
