Solar wind—the stream of charged particles flowing from the sun—is generating scientific intrigue as NASA's New Horizons spacecraft detects unexpected slowdowns at the solar system's edge, while researchers tackle mysteries about coronal heating and the role of cosmic dust in solar dynamics.
·New Horizons reveals hidden interstellar slowdown where solar wind encounters interstellar atoms adding drag
·Cosmic dust emerging as key factor in solving long-standing mystery of why the solar corona is so hot
·X1.1 solar flare activity monitored with geomagnetic storm watch issued
·Mars spacecraft anomalies hint at unexpected solar wind behavior previously overlooked by instruments
