Just like an orange! U.S. Observatory released the clearest sunspot photo in history

The world’s largest solar observatory recently released the clearest sunspot picture ever according to foreign media reports. Individuals can see the details of sunspot activity under the warm red and orange tones.

The Inoue Development Solar Telescope (DKIST) is still under construction in Hawaii, the world’s largest solar telescope, but the first sunspot picture taken on 28 January 2020 is also the clearest image of sunspots that can be seen.

Thomas Rimmerle, an astronomer at the United States National Solar Observatory, said The spatial resolution of this sunspot image is 2.5 times higher than before, showing the magnetic field structure of the sun as small as 20 kilometers.”

The diameter of this image is about 16,000 kilometers, according to the researchers. They were able to monitor improvements in fine structures in a short time period when they imaged the field (about 100 seconds).

The creation of sunspots is according to studies, caused by the emergence of the internal magnetic field of the sun on the surface of the photosphere. Since the intense magnetic field of sunspots suppresses plasma convection, the active region is smaller than that of the surrounding environment, so it appears cooler.
