Our star is already halfway through its life, but what happens when it disappears?

Built on the side of volcanoon the island of Mauiisles in Hawaii, the telescope solar Daniel-K.-Inouye, — that of National Science Foundation (United States) called before theAdvanced Technology Solar Telescope — considered to be most powerful telescope in the world intended to observe our Sun. 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 a glass 4 meters above sea level is located at 3,000 meters above sea level light pollution and commotion 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 the chromosphere in our Star. Understand the bass atmosphere of the sun. This layer of gas lies just above its visible surface.

One of the photos shows what is astronomers called solar granulation. The phenomenon was first known in the early 19th century.e century, by William Herschel. Convective cells, as researchers have known since the 1930s, are each about 500 to 1,000 kilometers in size. And to whom duration life is short. Only about ten minutes.

Another image, just as shocking, shows a variety of streaks that are actually nothing else jet of a plasma at 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 meteorology spatial.

While theEuropean Space Agency and the in an investigation is about to be launched Solar Orbiter in a few days and that the American Parker Solar Probe 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 cells of the convection which makes 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 according to the movements that occur under the surface of the Sun and that bring 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 a resolutions twice 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 it magnetic fieldin space time.
