New images from the world’s largest solar observatory have been released. The observatory is called the Daniel K Inouye Solar Telescope and is located on the Hawaiian island of Maui. The researchers took the picture on January 28, 2020, but it has only been released to the public now. The giant sunspot seen in the photo below is about 10,000 miles in diameter.
Scientists say the sunspot is wide enough for the Earth to fit in and leave a small room. The National Science Foundation owns the telescope and on Friday released the image along with a video of the sunspot. The researchers claim that the image of sunspots has a spatial resolution about 2.5 times higher than previously achieved.
The resolution allows the image to show magnetic structures on the surface of the sun only 20 kilometers. Although the telescope is the largest solar observatory in the world, it is still in the final stages of completion. The image shows how well the telescope’s advanced optics and four-meter primary mirror will allow scientists to observe the Sun in the next solar cycle.
The project’s scientists point out that the image is not the same sunspot that can now be seen in the sun with the naked eye. At this point, it is also worth noting that without special equipment you can not look directly at the sun. The article describing the sunspot in the image is the first in a series of articles in solar physics based on data collected by observatories.
The striped appearance in the darker center of the sunspot shows hot and cold gas being released from the darker center, and is the result of sculpture by the convergence of intense magnetic fields and hot gases coming from below. The dark sunspot is colder than the surrounding area of the sun, but it is still extremely hot at temperatures over 7,500 degrees Fahrenheit.
