The Daniel K. Inouye Solar Telescope of the United States Science Foundation recently released the first image of the sunspot, taken on January 28, 2020. The image shows how the advanced optics of the telescope and the four-meter primary mirror will give scientists the best view. From the Earth to the next full solar cycle.
The images show striking details of the structure of the Sun’s stain as seen on the Sun’s surface. The appearance of the hot and fresh gas line coming out of the dark area is the result of sculptures of the convergence of living magnetic fields and hot gases boiling below.
Dr. Thomas Rimmele, associate director of the NSF National Solar Observatory (NSO), said: “The image of the sunspot achieves a spatial resolution that was 2.5 times higher than ever before, showing a 20-kilometer magnetic structure on the sun’s surface.”
This image of the sunspot is just a small part of the Sun. It seems to be very small, but the fact is that our earth easily penetrates within that sunspot.
The concentration of magnetic fields in this dark region drowns out the heat of the Sun from reaching the surface. Although the dark region of the sunspot is cooler than the Sun’s area, it still exerts high heat with temperatures above 7,500 degrees Fahrenheit.
Dr. Matt Mountain, president of the Association of Universities for Astronomical Research (AURA), the organization that manages the NSO and the Inouye Solar Telescope, said, “At the beginning of this solar cycle, we are also entering the era of the Inouye Solar Telescope. We can point the world’s most advanced solar telescope at the Sun to capture and share highly accurate images and add our scientific insights into the Sun’s activity. ”
