太阳的日冕环

英文原文:Explanation: 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 small 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. Jigsaw Universe: Astronomy Puzzle of the Day 说明： 我们的太阳常发生环状的爆发。 造成炙热的太阳电浆[2]从其表面喷出，形成我们称为日珥[3]的结构，其中最常见的类型为单环日珥。 这些环形结构[4]源自太阳的磁场[5]，其轮廓由沿磁力线做螺旋运动的电子与质子交织而成。 许多日珥下层的日冕[6]环，大小足以包覆[7]整个地球，而且可稳定存续数天。 日冕环通常出现在太阳黑子[8]活跃区的附近。 这幅主题图像[9]所示的四个位于太阳[10]边缘的日冕环，摄于2024至2025年间。 这些图像由位于意大利[11] 曼托瓦[12]的一部小望远镜，摄于氢原子[13]发光的氢α[14]波段。 有时日珥会突然断裂[15]，并将高能粒子抛入[16] 太阳系[17]里，造成一系列的太空天气[18]事件，进而可能影响地球的天空[19]景观与各种电网[20]回路。
