   10 Αυγ 2016 · NASA's SDO spacecraft captured the image below in multiple wavelengths of extreme ultraviolet (EUV) radiation. The false-color composite reveals different gas temperatures. Reds are relatively cool (about 60,000 Celsius) while blues and greens are hotter (greater than one million Celsius).

   Electromagnetic radiation of shorter wavelength than visible radiation but longer than x-rays. Radiation in the interval 10 to 4000 angstroms. UV radiation from the sun is responsible for many photochemical ractions in the upper atmosphere especially the formation of ozone. UV-B radiation in the range 280-320 nm can possibly have serious health ...

   ultraviolet radiation. The energy range just beyond the violet end of the visible spectrum. Although ultraviolet radiation constitutes only about 5 percent of the total energy emitted from the sun, it is the major energy source for the stratosphere and mesosphere, playing a dominant role in both energy balance and chemical composition.
