Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known ... LAT Discovery of a Gamma-ray Outburst from the Peculiar Compact Steep Spectrum Radiogalaxy 3C 216 ...

An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers explain such phenomena.

There's lots to discover in the electromagnetic spectrum. Here's a tour that ... ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed ...

However, nothing would protect us, or the planet, from the most powerful source of gamma rays in the known universe ... narrow band of the electromagnetic spectrum (390 to 700 nanometers).

Figure caption, Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.
