Sun comes alive in HD images

Remarkable high-definition images of the sun taken by Nasa's space-based telescope, the Solar Dynamics Observatory (SDO) have been released.

The telescope took a high-resolution image of the sun every 12 seconds in ten wavelengths of invisible UV light, with each wavelength highlighting a different temperature and assigned a colour.

The images were put together and show several active regions of the sun, which are usually the source of solar storms.
