The Daniel K. Inouye Solar Telescope Produced the Highest Resolution Image of the Sun's Surface (IMAGE)
Caption
The Daniel K. Inouye Solar Telescope has produced the highest resolution image of the sun's surface ever taken. In this picture, taken at 789 nanometers (nm), we can see features as small as 30km (18 miles) in size for the first time ever. The image shows a pattern of turbulent, "boiling" gas that covers the entire sun. The cell-like structures -- each about the size of Texas -- are the signature of violent motions that transport heat from the inside of the sun to its surface. Hot solar material (plasma) rises in the bright centers of "cells," cools off and then sinks below the surface in dark lanes in a process known as convection. In these dark lanes we can also see the tiny, bright markers of magnetic fields. Never before seen to this clarity, these bright specks are thought to channel energy up into the outer layers of the solar atmosphere called the corona. These bright spots may be at the core of why the solar corona is more than a million degrees.

Usage Restrictions
The images and movies shown here are part of the facility Science Verification Phase. They are for the sole purpose of promotion and are not released for scientific use. Science Verification Phase data is proprietary to the DKIST project, and its use for publications or outreach purposes requires approval by the NSO Director, and notification to the cognizant NSF program officer. Please contact outreach@nso.edu for details and questions. The original data are still being processed and are not fully calibrated for scientific use. Images have been processed to remove noise and enhance the visibility (contrast) of small-scale (magnetic) features while maintaining their shape. The movie frames have been smoothed to remove noise.
