In the NEWS Surprising appearance of a huge hole in the surface of the Sun Translation of Article by, Natalie N. Sabatini The sun has begun this 2015 by presenting an unusual phenomenon on the surface: a massive coronal hole near the south pole, which can be perceived as a huge dark area. The image of the coronal hole was captured on January 1, 2015 by NASA. Coronal holes indicate regions of solar magnetic fields whose lines are dispersed in interplanetary space, instead of closing, reports Daily Mail. The particles of magnetic fields can disperse out of the sun and in space rather than be trapped near the surface. The trapped particles can overheat and burn, as seen in the image. In parts of the crown where the particles have left the sun, the brightness is significantly dimmer and the area is perceived as darker. Coronal holes were captured for the first time in images taken by astronauts on the NASA Skylab space station in 1973 and 1974. The hole in the polar corona, which is a peculiarity of the sun, may remain visible for five years or more . The material flowing outward from the sun is called a solar wind, which typically blows at around 400 km per second. However, when a coronal hole is present, the wind speed can bend and reach almost 800 kilometers per second. actualidad.rt/ciencias/162173-fenomeno-solar-superficie-agujero-coronal
