Using advanced algorithms, a team of scientists found never-before-detected, fine-grained structures in the Sun’s million-degree atmosphere, also known as the corona. This finding could help answer questions related to the stream of charged particles that flow outward from the Sun, known as solar wind. In deep space, the solar wind is turbulent and gusty, but how did it get that way? Did it leave the Sun smooth, and become turbulent as it crossed the solar system, or are the gusts telling us about the Sun itself? Answering this question requires observing the outer corona — the source of the solar wind — in extreme detail. If the Sun itself causes the turbulence in the solar wind, then we should be able to see complex structures right from the beginning of the wind’s journey.But existing data didn’t show such fine-grained structure — at least, until now.Credit: @NASA/Craig DeForest, SwRI#nasa #space #sun #solar #universe #solarsystem #wind #solarwind #earth #magentic #particles #dusty #windy #gif #particles #science #algorithm #dust #atmosphere #corona
