Scientists Spot Tiny Swirls on Sun for the First Time
The Sun is a giant ball of very hot glowing gas.
Scientists want to understand how it works.
They used a very powerful telescope on a mountain in Hawaii to look at the Sun.
The telescope showed the Sun's surface in amazing detail.
Scientists saw tiny spinning swirls there for the first time ever.
These little whirlpools happen when layers of gas move past each other at different speeds.
The swirls can twist the Sun's magnetic fields, like twisting rubber bands.
When those twisted fields snap, they release a burst of energy.
That energy can sometimes affect Earth, like disturbing satellites and power grids.
This discovery helps scientists solve mysteries about the Sun.
For the first time, scientists spotted tiny swirling patterns called Kelvin-Helmholtz instability on the Sun's surface.
The observations were made with the National Science Foundation's Daniel K Inouye Solar Telescope near the summit of Haleakala on Maui, Hawaii.
Images and time-lapse video captured unprecedented detail of the Sun's photosphere near a magnetically active sunspot.
The swirls may twist the Sun's magnetic field lines together, helping explain the buildup of energy behind solar flares and coronal mass ejections.
The findings were published in the journal Nature; the phenomenon was previously seen in ocean waves, clouds, and the atmospheres of Jupiter and Saturn.
- Who
- Scientists using the National Science Foundation's Daniel K Inouye Solar Telescope.
- What
- Captured the first observations of Kelvin-Helmholtz instability — tiny swirling patterns — on the Sun's surface.
- Where
- On the Sun's visible surface (photosphere), observed with the telescope near the summit of Haleakala on Maui, Hawaii.
