The Sun’s outflow of charged particles, long thought to be slowly fading, began to recover after 2008, a new analysis finds. Measurements at Earth’s orbit show steady increases in speed, density, temperature, pressure, and magnetic field strength, a shift with implications for the heliosphere, planetary magnetospheres, and space weather.
New 2025 study finds solar wind reversed its multi-decade weakening in 2008, rising in speed, density, pressure and magnetic field, reshaping the heliosphere.
