新研究发现太阳耀斑源于“磁雪崩”

Core Insights - A new study by the European Space Agency reveals that solar flares are triggered by weak and rapid disturbances in magnetic fields, which gradually escalate to create a "magnetic avalanche" [1] Group 1 - Solar flares are among the most intense events on the Sun, characterized by sudden brightening in localized areas of the solar surface [1] - These flares release massive amounts of energy, heating plasma to tens of millions of degrees and accelerating charged particles to near-light speeds [1]
