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 ...

An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang ...

Previous research also indicated that Earth looks down the axis of this system, known as Wolf-Rayet 104, raising concerns ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

Depending on the circumstances you find yourself in, a Geiger counter can be a tremendously useful tool. With just a click or a chirp, it can tell you if any invisible threats lurk. But a Geiger ...

An unusual gamma-ray burst has challenged existing astrophysical models, leaving scientists searching for answers. This deep-space event defies expectations, hinting at new cosmic processes we may ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

Broser and Kallmann 1 have shown that mono-energetic alpha-particles give pulses of the same height in a scintillation counter, and that the pulse-height is proportional to the energy of the alpha ...
