Built on the side ofon the island of Maui in Hawaii, the solar Daniel-K.-Inouye, — that of National Science Foundation (United States) called before theAdvanced Technology Solar Telescope — considered to be intended to observe our . And a few days ago, on the occasion of its official inauguration — it has been collecting scientific data for several months – the teams in charge of its operation published two new stunning images of our Star .
Their quality is particularly remarkable because we are not talking about a probe sent to “burn wings” near the Sun. But a telescope on the ground. With 4 meters of glass, located about 3,000 meters above sea level and protected fromand atmosphere through a marine environment.
The solar chromosphere in all its states
In two images published during the inauguration of the Daniel-K.-Inouye solar telescope, we discovered thein our star. Understand the bass . This layer of lies just above its visible surface.
One of the photos shows what iscall him . The phenomenon was first known in the early 19th century.e century, by . Convective cells, as researchers have known since the 1930s, are each about 500 to 1,000 kilometers in size. And whose life is short. Only about ten minutes.
Another image, just as shocking, shows a variety of streaks that are actually nothing elseat very high temperatures.
The face of the Sun as you have never seen it before!
The Daniel K. Inouye Solar Terrestrial Telescope recently captured its first images of the Sun. They are the most beautiful and the most beautiful the face of the Sun has ever been captured. This unprecedented ability to observe the Sun promises a remarkable leap in knowledge of the events at the beginning of its activity that influence thespatial.

While theand the getting ready to launch the investigation in a few days and that the American approached only 19 million kilometers from the Sun, it was a solar terrestrial telescope that made the news. In fact, the Daniel K. Inouye solar telescope (DKIST for Daniel K. Inouye Solar Telescope), set for commissioning this summer, captured the first and most accurate images of the Sun’s surface ever recorded. The smallest details that can be seen there are almost 30 kilometers in size! What, on the scale of the Sun, is a star roughly 1.4 million kilometers in diameter, is microscopic.
Convection cells in perpetual motion
What we see are the convection cells that make up the surface of the Sun. They measure more or less 1,000 kilometers in diameter and are constantly changing. They deform, appear and disappear accordinglywhich occurs below the surface of the Sun and which causes the hottest gas to rise from the interior of the star to the surface.

Built on Mount Haleakala on the island of Maui in Hawaii, DKIST is the world’s largest solar telescope capable of taking ultra-detailed images of the Sun’s surface, and it has atwice as long as other solar observatories in service. Until now, solar telescopes had mirrors with a diameter of up to 1.50 meters. This off-axis telescope is equipped with an active primary mirror of 4.2 meters in diameter, with thermal control and adaptive optics. DKIST is also the most technically complex solar telescope currently in service.
This telescope is designed to better understand the role of the Sun, especially itin space time.
