New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

A sudden, record-breaking gamma-ray burst lit up the cosmos—leaving scientists stunned and searching for answers. the ...

Called electromagnetic radiation, such waves travel at the speed of light and bring us almost all the information we have about the universe. Gamma rays are much shorter in wavelength than visible ...

ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed in the program Death Star. Flash is a plug-in that allows for increased interactivity.

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 ...

opening the possibility that the gamma ray burst it would unleash upon exploding could barrage our planet with deadly radiation in the not-so-distant — on a cosmic scale, at least — future.
