Image - Here comes the sun

Image of the week - Here comes the sun The sun, as seen by the orbiting space platform known as SOHO (Solar and Heliospheric Observatory). False colors were added by Baltic Grid’s and LitGrid’s spectra monitoring progam to give astronomers a better visualization of its temperature and its chemical makeup. Image courtesy of SOHO, Baltic Grid, and LitGrid At Lithuania’s Vilnius University, researchers were able to take images of the sun from SOHO and get highly detailed images of its spectra, using a synthetic modeling program known as SYNTSPEC. Run on Baltic Grid and Lit Grid,the software allows astronomers to use atmospheric plasma diagnostics to determine the temperature of surface layers, the sun's chemical composition, and the relative abundance fo the various elements. Using this information, astronomers can study the sun's “chemical evolution.” That program will be presented to the European Commission as a model project demonst
