The Solar Dynamics Observatory

22 Apr 2010

NASAs new Eye on the Sun delivers a series of stunning images at (and see also April 21st). Some images show material streaming away from sun spots - others are close-up images of the surface of the Sun. The spacecraft has also made high resolution measurements of solar flares in a range of ultra-violet wavelengths.

The Solar Dynamic Observatory is set to change understanding of the Sun and it's processes - and will impact science. It has a 5 year mission to examine the Sun's magnetic field and provide information on  how the Sun affects the atmosphere of the Earth - and therefore our climate.
