'Superfast' solar winds lead to 'square-shaped' dark spot on sun
A new study has revealed that super solar winds streaming from the sun cause the square dark spot known as a "coronal hole".
A NASA spacecraft has made a surprising find on the surface of the sun and the square-shaped "hole" in the star's outer atmosphere," is an area where the solar wind is streaming out of the sun at superfast speeds, Mashable reported.
The coronal hole appears dark because there is less material emitting light in the ultraviolet range of the spectrum used to make the video.
NASA's sun-watching Solar Dynamics Observatory is just one of a fleet of spacecraft keeping a close watch on the weather on Earth's parent star.
