Sun - Handle-shaped Prominence

Extreme Ultraviolet Imaging Telescope (EIT) image of a huge, handle-shaped prominence taken on Sept. 14,1999 taken in the 304 angstrom wavelength - Prominences are huge clouds of relatively cool dense plasmasuspended in the Sun's hot, thin corona. At times, they can erupt,escaping the Sun's atmosphere. Emission in this spectral line shows theupper chromosphere at a temperature of about 60,000 degrees K. Everyfeature in the image traces magnetic field structure. The hottest areasappear almost white, while the darker red areas indicate coolertemperatures.
