Die Sonne in der höchsten Auflösung ever… ☀️
Aufnahmen die näher dran waren an der Oberfläche der Sonne hat es nie gegeben. Die Linse des ‚Daniel K. Inouye Solar Telescope‘ ist bis auf ca. dreißig Kilometer an den glühenden Ball herangekommen.

The Daniel K. Inouye Solar Telescope has produced the highest resolution observations of the Sun’s surface ever taken. In this movie, taken at a wavelength of 705nm over a period of 10 minutes, we can see features as small as 30km (18 miles) in size for the first time ever. The movie shows the 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! This movie covers an area 19,000 x 10,700 km (11,800 x 6,700 miles or 27 x 15 arcseconds)
