Very cool SOHO Images

EIT 171EIT 195EIT 284EIT 304

EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, showing solar material at different temperatures. The orange image is taken at 304 Angstroms with the bright material being 60,000 to 80,000 Kelvin. The blue image is taken at 171 Angstroms showing 1 million Kelvin. The green image is taken at 195 Angstrom showing 1.5 million Kelvin. The yellow image is taken at 284 Angstrom showing 2 million kelvin. By the way, Kelvin is A unit of absolute temperature. Zero degrees Celsius is equal to 273 Kelvin. Zero Kelvin is "absolute zero" - the coldest temperature possible.
