"In images of the Sun coming from space at this exact moment, a large coronal hole with a lateral dimension of about a million kilometers was observed," the scientists reported. According to experts, the phenomenon represents a vast region of the solar atmosphere where the temperature and density of the plasma is significantly reduced.
