US · Published Jul 7, 2026
Scientists may have uncovered a key factor in the mystery of why the Sun's corona, its outer atmosphere, is significantly hotter than its surface.
Research led by Syed Ayaz from the University of Alabama in Huntsville suggests that cosmic dust grains, interacting with the Sun's electromagnetic field, could play a role in heating the corona.

Impact & Risks

This discovery could reshape our understanding of solar physics and the mechanisms driving the Sun's energy distribution. The findings suggest that cosmic dust, previously overlooked, may significantly influence the behavior of plasma and electromagnetic fields in the Sun's atmosphere. This has implications for future solar missions, which may need to include dedicated dust detectors to better understand these interactions. While the research does not pose immediate risks, it highlights the complexity of solar phenomena that can impact space weather, potentially affecting satellites, communication systems, and power grids on Earth.
