Previously Hidden Plasma Traps Discovered on the Sun’s Surface
Astronomers from the U.S. National Solar Observatory have obtained the most detailed images of the Sun’s surface ever captured. This was made possible by the world’s largest solar telescope, the Inouye Solar Telescope, located atop a volcano on the island of Maui, Hawaii. The instrument takes several images per second, and its resolution is three times higher than that of previous models.
The most important discovery was an explanation of the mechanism behind plasma vortices caused by Kelvin–Helmholtz instability.
The funnels range from 500 to 2,000 kilometers in diameter, which is microscopic on the scale of the Sun. They can now be observed in unprecedented detail.
Key Findings and Their Significance
These hot, rotating vortex traps accumulate and release energy, altering the magnetic field on the Sun’s surface. This helps explain space weather, solar flares, the formation of prominences, and bursts of solar energy.
The discovery could have practical implications: solar storms can disrupt satellites and power grids on Earth.
Astrophysicist David Boboltz of the National Solar Observatory hopes that studying plasma vortices will help scientists better understand the dynamics of the Sun’s surface and move toward more accurate space weather forecasting.
The study’s findings were published last week in a leading scientific journal.
Changes in our understanding of the dynamics of the Sun’s surface could open up new approaches to forecasting space phenomena that directly affect technologies and systems on Earth.
