Posnetek predstavlja animacijo fotografij Sonca v ultravijolični svetlobi, ki jih je 11.7.2016 posnel satelit NASA’s Solar Dynamics Observatory. Več o pojavu “luknje v koroni Sonca” lahko preberete tule: Coronal hole in NASA just found a huge hole growing on the surface of the Sun.
According to NASA, these holes mark low-density spots where the sun’s magnetic field opens freely into interplanetary space, allowing hot material from the corona to speed outward. Because of this, the areas have much less hot plasma than their hotter, brighter surroundings, causing them to appear dark and, well, ‘hole-y’.
