"Breakthrough: Elusive Alfvén Waves Unveiled in Sun's Corona"

Researchers have unveiled direct evidence of small-scale torsional Alfvén waves in the stellar corona of the Sun, marking a significant advancement in solar physics.

The breakthrough was achieved using the Daniel K. Inouye Solar Telescope, operated by the National Science Foundation, allowing unprecedented observations in the stellar atmosphere.
This discovery of Alfvén waves provides insights into plasma (physics) in the Suns stellar corona, a phenomenon scientists have sought since the 1940s.
Understanding Alfvén waves could enhance knowledge of electromagnetism and energy transfer processes occurring in the Sun, impacting solar and space weather predictions.

Why It Matters

This discovery is pivotal for advancing our understanding of solar dynamics and the behavior of plasma (physics), which can have significant implications for space weather forecasting and technology on Earth.
