Solar prominences. Composite of four SOHO images of the Sun showing solar prominences,dense clouds of plasma in the Sun's atmosphere (corona). Clockwise from top left,the images were taken on 15th May 2001,28th March 2000,18th January 2000 and 2nd February 2001. The images are taken in the light of ionised helium,at a wavelength of 30.4 nanometres. This corresponds to a temperature of around 60,000 Kelvin. The clouds of plasma are constrained by the Sun's magnetic field,causing them to have looped and twisted shapes. Large prominences can cause electrical blackouts and auroral storms if directed towards Earth. Images taken by the EIT on the SOHO spacecraft | |
