How to see the sun! Solar telescope captured the image of full eclipse! There is also corona in the sun

Hawaii Island: The sun is constantly shining. And the flame of life is burning in the flame of that combustion, this is eternal truth. But there is no end to people’s curiosity about what exactly the sun looks like. NASA had earlier released several images and short videos that revealed detailed images of the Sun’s surface to the public. But there was more to the surprise. That came to light recently.

DKIST or ‘Daniel K. Inouye Solar Telescope’ (Daniel K. Inouye Solar Telescope) installed in Hawaii Islands has taken some pictures that can surprise. These images show a clear picture of the Sun’s ‘chromosphere’ for the first time. The chromosphere is the atmosphere just above the Sun’s surface. These images were taken by the Solar Telescope last June 3, 2022. An area of ​​about 82,500 km has been captured in the images at a resolution of 18 km.

What is Chromosphere?

The outermost part of the Sun’s atmosphere is called the Corona. And the very part of the sun’s surface is called the chromosphere. It is mostly covered by the sun’s ‘photosphere’ or the sun’s luminous outer cloud. The images that the telescope took were all during total eclipses. At that time the scattered light from the photosphere was largely blocked by the Moon’s shadow. As a result, the region appeared as a bright red ring outside the core of the Sun.

One of the goals of this research is space weather, super bright solar flares and coronal mass ejections that are spreading into space. NSF Director Sethuraman Panchanathan said, ‘NSF’s Inouye Solar Telescope is one of the world’s most powerful solar telescopes that will shatter our old assumptions about the Sun. Solar storms will also change the way we predict the future of our planet.’

Daniel K. The Inoue Solar Telescope, or DKIST, is located near the Haleakala Observatory on the island of Hawaii in Maui. The peculiarity of this place is that it has long day length, which is essential for a solar telescope. In addition, clear skies can be found at altitudes of about 10,000 feet (3,000 meters) in oceanic environments, ideal for viewing the Sun’s corona and chromosphere. In this environment there is supposed to be no dust in the Earth’s atmosphere.

DKIST uses mirrors that have never been used in any solar system on Earth. At 13 feet (4 meters) wide, this mirror can capture a large amount of sunlight. As a result we can see very clear high resolution images.
