What’s happening to our Sun? Another Coronal Mass Ejection (CME)! The Sun-orbiting SOHO spacecraft has imaged many erupting filaments lifting off the active solar surface and blasting enormous bubbles of magnetic plasma into space. Direct light from the sun is blocked in the inner part of the featured image, taken in 2002, and replaced by a simultaneous image of the Sun in ultraviolet light. The field of view extends over two million kilometers from the solar surface. While hints of these explosive events, called coronal mass ejections or CMEs, were discovered by spacecraft in the early 70s, this dramatic image is part of a detailed record of this CME’s development from the presently operating SOHO spacecraft. Near the maximum of the solar activity cycle, CMEs now typically occur several times a week. Strong CMEs may profoundly influence space weather. Those directed toward our planet can have serious effects. Astrophysicists: Browse 1,100+ codes in the Astrophysics Source Code Library

🌞 最近太陽發生咗啲咩事？又有一次日冕物質拋射（CME）！圍繞太陽運行嘅SOHO太空船拍攝咗好多火焰噴發，將大量的磁場等離子體噴射到太空中。圖像中，直接來自太陽的光在內部被遮擋，取而代之的是太陽在紫外光下的同時影像。圖像範圍延伸超過兩百萬公里離太陽表面。
早喺70年代初期，太空船首次發現咗這些爆炸事件，但呢幅戲劇性嘅圖像來自運作中嘅SOHO太空船，詳細紀錄咗呢次CME的發展。在太陽活動週期達到巔峰嘅時候，CME通常每星期會發生幾次。而強烈的CME可能會對太空天氣造成深遠影響，特別係如果佢哋正對著我們的星球，可能會引起嚴重後果。
