A Self-Guided Tour of the Electromagnetic Spectrum : Gamma rays 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 ...

The study, “Revealing x-ray and gamma ray temporal and spectral similarities in the GRB 190829A afterglow”, has been published in Science. More about Star Scientists Radiation satellites ...

Our Sun emits light at progressively shorter wavelengths, too: the ultraviolet, X-ray, and even gamma-ray parts of the spectrum. But most of the Sun’s light is in the infrared, ...

Diagram of the process by which high-energy gamma rays were annihilated by ultraviolet light from the earliest stars. ... then there would be a stronger cutoff in the gamma ray spectrum.

Gamma-ray bursts are among the most powerful events in nature. These events release most of their energy as photons with energies in the range from 30 keV to a few MeV, with a smaller fraction of ...

There's lots to discover in the electromagnetic spectrum. Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays.
