Solar Corona Heat Mystery Explained by NASA's Parker Probe
The heat of the solar corona remains one of the biggest mysteries in astrophysics, reaching millions of degrees Celsius despite its distance from the Sun's surface, which is about 5,500 degrees Celsius. Data from the Parker spacecraft has revealed that cosmic dust grains may contribute to increasing the corona's temperature through electrical interactions with plasma waves, explaining the high temperatures in certain regions of the Sun’s outer atmosphere. This discovery could improve our understanding of how energy is transferred within the Sun and impact future studies on solar energy and the influence of dust on solar phenomena.
