"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 ...

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 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 ...

BurstCube may be small, but it has a big mission. NASA scientists will use the satellite to identify, pinpoint, and analyze short gamma-ray bursts, which are brief and strong flashes of light.

PGAA is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma-ray emissions. Inaccurate and incomplete ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
