Nasa Spots ‘Square Hole’ In The Sun’s Surface

A near-perfect square ‘hole’ in the sun has been caught on camera by NASA.211_cor_hole.jpg

An updraft of solar winds ripped the shape in the sun’s outer atmosphere, and the results were spotted by the agency’s Solar Dynamics Observatory which monitors the star.

The dark spot is known as a coronal hole, and is made when solar winds pull away from the sun at incredibly high speeds.

It appears dark in ultraviolet light because there is less material to emit the wavelengths.

Nasa said: “A coronal hole is an area where high-speed solar wind streams into space.

“Inside the coronal hole you can see bright loops where the hot plasma outlines little pieces of the solar magnetic field sticking above the surface.”
