An infrared image released by Eumetsat on May 22, 2011 shows the invisible infrared radiation emitted directly by cloud tops and land or ocean surfaces over Europe this morning. The warmer an object is, the more intensely it emits radiation, thus allowing us to determine its temperature. These intensities can be converted into greyscale tones, with cooler temperatures showing as lighter tones and warmer as darker. Iceland's airspace temporarily closed down early on May 22 because of a violent eruption of the country's most active volcano, the airport administration Isavia said. AFP PHOTO / EUMETSAT-MET OFFICE
