这个奇怪的黑球看起来眼熟吗？如果是这样，那可能是因为它是我们的太阳。在2012年的特色图像中，详细的太阳视图最初以非常特定的红色拍摄，然后渲染为黑色和白色，然后反转颜色。一旦完成，生成的图像被添加到星场，然后也颜色反转。在太阳的图像中可以看到长长的光丝，黑暗的活动区域，日珥的边缘，以及热气体的移动地毯。太阳表面可能是一个繁忙的地方，特别是在太阳活动极大期，这是太阳表面磁场最活跃的时候。除了活跃的太阳如此美丽之外，当它撞击地球的磁层并产生极光时，释放的等离子体也会变得美丽。自己计算：浏览天体物理源代码库中的2,900多个代码

Does this strange dark ball look somehow familiar? If so, that might be because it is our Sun. In the featured image from 2012, a detailed solar view was captured originally in a very specific color of red light, then rendered in black and white, and then color inverted. Once complete, the resulting image was added to a starfield, then also color inverted. Visible in the image of the Sun are long light filaments, dark active regions, prominences peeking around the edge, and a moving carpet of hot gas. The surface of our Sun can be a busy place, in particular during Solar Maximum, the time when its surface magnetic field is wound up the most. Besides an active Sun being so picturesque, the plasma expelled can also become picturesque when it impacts the Earth's magnetosphere and creates auroras.
