太陽這顆星星經常會冒出熱熱的火花，就像撲通撲通的心一樣！這些熱的太陽氣體噴射到太陽的表面，形成了漂亮的「環」形狀，這就是太陽的「日冕」。這些環的形狀是由太陽的磁力生成的，就像是太陽在操控著一種隱形的力量！這些環有些非常巨大，甚至可以把地球包住，還會持續好幾天！它們通常會在太陽的活躍區域出現，這些地方還有一些黑黑的陽光斑點。故事的圖片展示了四個環，這些照片是在2024年和2025年於義大利的Mantova拍攝的，特別是用一種主要是由氫氣發出的顏色來捕捉的。 有時，這些太陽的環會突然爆裂，噴出粒子到太空中，造成的太空天氣變化可能會影響地球的天空和電線。我們可以想像，這就像太陽在給我們發送了一封特別的宇宙明信片！

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.
