`` Image of the sun's surface '' shot at the highest resolution ever released
By
On January 29, 2020, the U.S. National Science Foundation (NSF) photographed the sun about 150 million kilometers away from Earth, photographed by the Daniel K. Inouye Solar Telescope (DKIST) built on Maui, Hawaii. The surface video has been released. The NSF says that the study will greatly enhance our understanding of the 'sun mystery.'

The actually released movie is as follows. The cells seem to be clustered together, but each cell is about the size of Texas, which boasts 1.8 times the area of Japan. The cells appear to be moving because they have caught the boiling surface of the atmospheric plasma layer.
The sun, the closest star to Earth, is a huge nuclear reactor that burns about 5 million tons of hydrogen per second. Solar activity has been around for about 5 billion years, and is estimated to continue for 4.5 billion years. The light from the sun has given birth to life on the earth. However, there are some solar activities such as ' solar flare ' that have an adverse effect on humankind, and the necessity of studying solar activity has been called for. Solar flares are a phenomenon that has a great effect on electronic devices such as computers, and it has been found that in the past, 'mines' installed underwater were detonated.

To observe such solar activity, NSF has installed the world's largest solar telescope, DKIST, with a total length of 4 meters, at the top of Mt. Haleakala, an altitude of about 3,000 meters, which means 'house of the sun' in Hawaiian. DKIST is equipped with a cooling device using ice generated at night and wind cooling devices such as more than 100 wind cooling devices as countermeasures against the huge heat generated by condensing when focusing on the sun.

An image of the sun's surface taken by DKIST has already been released, but we plan to add equipment to measure the magnetic field from the sun's surface to the ground by adding additional functions.

NSF says, 'Understanding the sun-generated space weather is more than 50 years behind ground-based weather. We will use DKIST to understand the underlying physics behind space weather. 'If we understand solar activity, we may be able to detect the occurrence of solar flares much earlier than we can today. If we can detect solar flares in advance, we can protect important infrastructure such as power grids. So you can spend more time on it. '
