The video shows images captured by the Solar Dynamics Observatory over 24 hours on September 25, 2011, emphasised in vivid blues, greens and yellows.
“There’s no science behind [adding the colours],” says Scott Wiesinger of Goddard Space Flight Centre, “But it looks very pretty.”
The authentic frames are in the 171 Angstrom wavelength of intense ultraviolet which exhibits plasma on the surface of sun at about 600,000 Kelvin.
“This video takes SDO images and applies additional processing to enhance the structures visible,” said a Nasa spokesperson.
“While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun.”

Nasa’s Solar Dynamics Observatory is an ‘eye’ in space focused on the sun – but its scientists have found an all-new way of looking at the star that gives our planet heat and life. Don’t be deceived by the calming blues and browns – the boiling surface of the star is around 600,000 degrees centigrade, just viewed through a wavelength that…
