Sun's Surface Mirrors Van Gogh's Starry Night
5 Aug
Summary
- Highest-resolution images show sun's photosphere with swirling patterns.
- These solar vortexes are identified as Kelvin-Helmholtz instability.
- Observations may explain solar eruptions impacting Earth technology.
Astronomers have achieved a significant breakthrough by obtaining the highest-resolution images of the sun's visible surface. These images reveal continuously growing whirls of hot plasma, exhibiting swirling, vortex-like patterns.
The observed phenomenon has been identified as Kelvin-Helmholtz instability (KHI), a dynamic process occurring when fluid streams interact at different velocities. This is the first detection of KHI on a star's surface, offering new insights into solar physics.
These KHI manifestations, measuring up to 100 miles in diameter, are driven by hot plasma and magnetic fields. Researchers believe they play a crucial role in energizing the sun's atmosphere and triggering explosive events.
The discovery provides a new framework for understanding solar energy dynamics. It could help explain solar flares and coronal mass ejections, which release energy and particles into space, potentially affecting Earth's technology.
Visually, the solar vortexes bear a striking resemblance to artistic depictions of turbulent skies, such as Vincent van Gogh's "The Starry Night" and Hokusai's "The Great Wave off Kanagawa."
