Latest Gamma ray Stories
The HAWK is field gamma spectrometer based on high purity germanium technology.
A new experiment aboard the International Space Station (ISS) is looking into the strange things that come from the tops of thunderstorms. The experiment, called "Firestation" consists of a package of sensors designed to explore how the Earth mimics a supernova during thunderstorms.
A new study has resurrected the hypothesis that cosmic rays may influence cloud formation on Earth.
Streaming across the Universe are high-energy charged particles, known as cosmic rays. For more than their origins have remained a mystery.
A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov Gamma Ray Observatory is designed to study the origin of very high-energy cosmic rays and observe the most energetic objects in the known universe.
Having successfully completed its five-year primary mission, NASA’s Fermi Gamma-ray Space Telescope entered the extended phase of its mission earlier this month – a deeper analysis of the high-energy cosmos that the US space agency hopes will continue through the year 2018.
NATS Incorporated in conjunction with its technical partners expands its radiation detection product lines to feature several systems for radiation monitoring of seawater which includes On-line,
Gamma-ray bursts are thought to be the most powerful, energetic events in the Universe. They can release as much energy in one second as an entire galaxy expels in an entire year.
A gamma-ray burst (GRB) created by the collision of two neutron stars has given researchers new insight into how gold, one of the rarest elements on Earth and in the entire universe, is formed.
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...
