M17 Swan Nebula

M17 or Swan Nebula was captured using the COAST telescope on Tenerife. Previous I edited the pictures using webeditor and downloaded the file in PNG format. Final editing was done using CS4 but it was difficult to allign the pixels from the different filter pictures. As the pictures are also available as Fits files I downloaded these to my pc and transformed the format to Tiff using Fits Liberator : see this link. 
Once the tiff files saved, CS4 was used to allign and to edit the picture. Below the result; personally I'm very pleased with it.

Coronal Mass Ejection and Earth's magnetic fields

Illustration of a CME from the Sun’s surface in the direction of Earth. The blue waves around the Earth’s poles represent it's magnetic field lines. The CME and it's magnetic cloud of plasma can extend to 45 million km wide by the time they reach Earth. These CME storms can disrupt communications and navigational equipment, damage satellites, and even cause electrical blackouts; and this is the science of Space Weather.
