Mystery at the sun’s south pole: Nasa reveals huge ‘coronal hole’ on the solar surface where winds reach 500 miles per SECOND

There were no fireworks on the sun to welcome in the New Year – and in fact, scientists say the end of the year was relatively quiet on the solar surface.

However, the sun has started 2015 with a mysterious event – a huge hole has appeared.

Known as a coronal hole, the phenomenon occurred near the south pole – and is seen as a dark area covered all of its base in these stunning images.

Coronal holes are regions of the corona where the magnetic field reaches out into space rather than looping back down onto the surface – and eject solar winds far faster than other parts of the sun.

The incredible image was  captured on Jan. 1, 2015 by the Atmospheric Imaging Assembly (AIA) instrument on NASA’s Solar Dynamics Observatory, shows the coronal hole as a dark region in the south.

Coronal holes are regions of the…
