New Horizons Watches the Solar Wind as it Slows Down

Researchers are zeroing in on the boundary where the Solar System transitions into interstellar space by observing the solar wind's behavior using New Horizons' instrument. As the solar wind slows down, it provides crucial data about the heliosphere's edge, offering insights into the interaction between our solar system and the broader cosmos. This research not only helps determine where the Sun's influence wanes but also sheds light on the interstellar medium's effects on our solar neighborhood. Understanding this boundary is key to comprehending space weather and its impact on both Earth and beyond.
