Observation of a Large Hole on the Sun

The American space agency, NASA, has announced that it has observed a very large black hole on the surface of the Sun. Although this hole is very large, scientists have stated that the Sun is neither cooling down nor exploding, so there is no cause for concern! These types of holes, known as coronal holes, are actually areas with low density in the Sun's atmosphere, which is called the coronal atmosphere. Since they contain less solar material, their temperature is lower than that of the surrounding material, making them appear much darker. Coronal holes are visible in certain types of ultraviolet rays, which cannot be seen with the naked eye and are only visible as purple. According to the Huffington Post, NASA has stated that coronal holes, which can sometimes remain in the Sun's atmosphere for weeks, can cover up to a quarter of its surface. Coronal holes are sources of high-speed solar particle winds that can sometimes burst from the surface of the Sun at speeds three times that of normal winds. These solar storms can disrupt the operation of satellites and radio waves moving around the Earth.
