Here comes the sun: Astonishing 'whip' half a million miles long spotted on 
solar surface (and scientists say radiation from it is heading for earth)
Radiation from the eruption set to hit earth within hours, creating a 'moderate 
geomagnetic storm'
Incredible phenomenon could give new insight into how solar eruptions affect 
electricity supplied on earth

Nasa today released stunning video showing a 500,000 mile long 'solar whip' on 
the surface of the sun - and say radiation from it is headed for eath.
Captured by from NASA?s Solar Dynamics Observatory (SDO), it shows a very long, 
whip-like solar filament extending over half a million miles in a long arc 
above the sun?s surface.

long, whip-like solar filament in the centre of the image, extending over half 
a million miles in a long arc above the sun's surface
WHAT IS A 'SOLAR WHIP'?
A 'solar whip' or filament is caused when a red glowing loop of plasma erupts, 
releasing the plasma out in huge loops hundreds of thousands of miles into 
space.
The filaments are anchored to the Sun's surface in the photosphere, and extend 
outwards into the Sun's hot outer atmosphere, called the corona.
The filaments are cooler clouds of solar material that are tethered above the 
sun?s surface by unstable magnetic forces.
The image and video (below), which covers August 6 to 8, 2012 show the filament 
as a darker strand that has been in view for several days.
'Towards the end of the video part of the filament seems to break away, but its 
basic length and shape seem to have remained mostly intact,' says Nasa.
The video, which condenses three hours of activity, also reveals the action in 
dramatic detail in extreme ultraviolet light.
Today it emerged the eruption was so large it will reach earth.
The NOAA spaceweather prediction center estimates that a cloud of radiation 
from the eruption will reach Earth today. 
The radiation cloud will create a minor to moderate geomagnetic storm, bringing 
the northern lights to parts of North America.

The video also reveals what the filament looks like closer to the surface of 
the sun
Nasa says the image is a classic example of a solar prominence (also known as a 
filament when viewed against the solar disk).
This is a large, bright feature extending outward from the Sun's surface.
Prominences are anchored to the Sun's surface in the photosphere, and extend 
outwards into the Sun's hot outer atmosphere, called the corona.
A prominence forms over timescales of about a day, and stable prominences may 
persist in the corona for several months, looping hundreds of thousands of 
miles into space.
However, scientists are still researching how and why prominences are formed.
The red-glowing looped material is plasma, a hot gas comprised of electrically 
charged hydrogen and helium. 
The prominence plasma flows along a tangled and twisted structure of magnetic 
fields generated by the sun?s internal dynamo. 
An erupting prominence occurs when such a structure becomes unstable and bursts 
outward, releasing the plasma

This image of a previous solar filament of the sun's surface shows the scale of 
eruptions.

The video (below) shows all the action in dramatic detail in extreme 
ultraviolet light. Here, the whip can be seen in the lower left of the image

The flare can be seen growing in the video before erupting in a 'whip'
