Nasa has discovered a 75000 mile-wide hole in the sun

Forecasters from the NOAA say that there is a 25 per cent chance of M-class flares today because the sunspot is directly facing our planet

Nasa has spotted a large black dot on the surface of the sun which is 74,560 miles wide - nearly 11 times larger than Earth's diameter.

They may look small, but shouldn't be underestimated, because sunspots are actually larger than the Earth.

Sunspots are darker, cooler areas on the surface of the sun, caused by interactions with the sun's magnetic field.

The sunspot, named AR2665, is 74,560 miles (120,000 kilometres) wide and big enough to be seen from Earth.

The storm has been monitored by Nasa's Solar Dynamics Observatory over the last week.

Due to the drop in solar activity, the sun was speckle-free for two days before this swirling sunspot appeared.

Sunspots are not rare but as our host star approaches the solar minimum or the least active part of its eleven-year cycle, the occurrence of sunspots declines.

The dynamic little trail of spots appears on the left of the screen as the glowing orange sphere spins around and slowly progresses across the screen in footage captured between July 5 and July 11, its shape shifting slightly as it goes-like an organism undulating under a microscope.

This image of a massive sunspot on the sun shows the full size of the feature as compared to the Earth (inset). They are a common phenomenon, and through scientists aren't entirely sure what causes them, they know that they're more frequent when the sun produces its most magnetic activity, known as the solar maximum.
