Latest Gamma ray Stories
Fermi scientist has transformed LAT data of a famous pulsar into a mesmerizing movie that visually encapsulates the spacecraft's complex motion.
Ohio State University cancer researchers have identified molecules in the bloodstream that might accurately gauge the likelihood of radiation illness after exposure to ionizing radiation.
A major step forward in our understanding of the structure and behavior of some of the most elusive atomic nuclei in existence, some of which occur only briefly on the surface of exploding stars, is now taking place thanks to the first experiments to come from the new Advanced Gamma Tracking Array (AGATA).
According to a new study, black hole cosmic radiation blasted into the Earth back in the 8th century. Japanese astrophysicist Fusa Miyake discovered last year clues for the strange event located in the rings of ancient cedar trees that dated back to either 774 or 775 AD.
NASA’s Fermi Gamma-ray Space Telescope, the most advanced space-based gamma-ray mission ever launched is turnings its eye to the problem of dark matter.
A multinational team of scientists has revealed new information about the explosive events known as novae.
According to new research led by Michigan Technological University, spacetime might be less like a foamy beer and more like a smooth Einsteinian whiskey.
The source of a gamma ray flare that shot past Earth throughout much of 2011 has been discovered, and contrary to popular theory, they did not occur close to their galaxy’s central black hole, say NASA officials.
Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
Hypernova -- A hypernova is a theoretical type of supernova produced when exceptionally large stars collapse at the end of their lifespan. In a hypernova, the core of the star collapses directly into a black hole and two extremely energetic jets of plasma are emitted from its rotational poles at nearly light speed. These jets emit intense gamma rays, and are a candidate explanation for gamma ray bursts. Theorists have come up with several plausible explanations for hypernovae. It may...
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
