Charged Dust Near the Sun May Change How Its Outer Atmosphere Gets Hotter Than Its Surface

Charged dust detected by the Parker Solar Probe is shedding light on a long-standing mystery about why the Sun's corona is significantly hotter than its surface. This discovery suggests that tiny particles carrying electric charge might play a role in heating the corona. Understanding this process could revolutionize our knowledge of solar physics and impact studies on space weather and its effects on satellites and communications. The implications extend beyond just scientific curiosity, as they could influence our ability to predict and mitigate solar events' impact on Earth.
