Gamma-Ray Astronomy

The study of the most energetic wavelength, or frequency, of electromagnetic radiation. Gamma-rays have wavelengths smaller than 10^-11 meters and frequencies greater than 10^20 Hz. They can be quite harmful to life because they are strong enough to ionize atoms and thus destroy cells. Fortunately, Earth's atmosphere shields us from most astronomical gamma-ray radiation.
