The smaller coronal hole, towards the opposite pole, is long and narrow, covering about 3.8 billion square miles on the sun - only about 0.16-percent of the solar surface.
'Coronal holes are lower density and temperature regions of the sun’s outer atmosphere, identified as the corona,' explained Nasa.
'Coronal holes can be a source of fast solar wind of solar particles that encircle the Earth.'
The magnetic field in these regions stretches far out into space rather than quickly looping back into the sun’s surface.
Magnetic fields that loop up and back down to the surface can be seen as arcs in non-coronal hole regions of the image, including over the lower right horizon.
The bright active region on the lower right quadrant is the same area that produced solar flares.
It is the second time Nasa has detected a huge hole on the sub. 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. Coronal holes were first seen in images taken by astronauts on board NASA's Skylab space station in 1973 and 1974.
They can be seen for a long time, although the accurate shape changes all the time.
The aforementioned solar storm that reached Earth Tuesday, contributed to a display of the aurora, lights as seen in the sky, stretching as far south as Oregon in the US, as well as being visible across the southern hemisphere.
Two blasts of magnetic plasma left the sun on Sunday, eventually combining and arriving on Earth on Tuesday about 15 hours earlier and much stronger than expected, said Thomas Berger, director of the Space Weather Prediction Centre in Boulder, Colorado.
Here are the amazing visuals as captured by people across the planet from north to south.
