我们的太阳经常以循环的形式爆发。热的太阳等离子体从太阳表面跃出，形成日珥，最常见的日珥是一个简单的环。圆环的形状源于太阳的磁场，它是由螺旋电子和质子追踪的。进入太阳下日冕的许多环足够大，可以包裹地球，并且足够稳定，可以持续几天。它们通常发生在活动区域附近，也包括暗太阳黑子。特色面板显示了四个环，每个环都是在2024年和2025年期间在太阳边缘附近捕获的。这些图像是由意大利曼托瓦的一架个人望远镜拍摄的，主要由氢发出的一种非常特殊的颜色的光。一些太阳日珥突然破裂，将粒子喷射到太阳系中，形成了一个可以影响地球天空和电线的空间天气序列。拼图宇宙：每日天文谜题

Our Sun frequently erupts in loops. Hot solar plasma jumps off the Sun's surface into prominences, with the most common type of prominence being a simple loop. The loop shape originates from the Sun's magnetic field, which is traced by spiraling electrons and protons. Many loops into the Sun's lower corona are large enough to envelop the Earth and are stable enough to last days. They commonly occur near active regions that also include dark sunspots. The featured panel shows four loops, each of which was captured near the Sun's edge during 2024 and 2025. The images were taken by a personal telescope in Mantova, Italy and in a very specific color of light emitted primarily by hydrogen. Some solar prominences suddenly break open and eject particles into the Solar System, setting up a space weather sequence that can affect the skies and wires of Earth.
