It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

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 ...

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.

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have ... swirling dust that glows in the infrared spectrum, the astronomers found.

A different spectrum of gamma rays represents each as part of the ... another part of the light curve could be described as ...
