New Horizons Data Explains Solar Wind Slowdown at Solar System's Boundary

Data from NASA's New Horizons spacecraft has provided new understanding of why the solar wind decelerates as it approaches the edge of our solar system. Researchers found the solar wind's speed was significantly slower at 58 AU from the Sun, a phenomenon attributed to its interaction with and absorption of interstellar neutral gas particles. These findings align with existing models and could help predict the heliosphere's boundaries and inform future deep-space missions regarding cosmic radiation.
