2013-11-04 15:33:49

Lee Rannals for redOrbit.com - Your Universe Online NASA’s FireStation instrument aboard the International Space Station (ISS) is helping scientists learn more about the party taking place inside a thunderstorm. The Space Test Program-Houston 4-FireStation is an instrument attached to the outside of the space station that is sponsored by NASA and the National Science Foundation (NSF). The instrument collects data as it flies over thunderstorms, helping scientists answer questions about...

The HAWK is field gamma spectrometer based on high purity germanium technology. The HAWK has been designed to bridge the gap in commercially available solutions by offering the customers an affordable solution devoid of the the disadvantages of the more expensive systems in the market. Middletown, Connecticut (PRWEB) September 18, 2013 Commercially available high resolution field Gamma Spectrometers are either too heavy for field use or are priced beyond the budgets of most users...

NASA Firestation To Track Strange Things Produced By Thunderstorms
2013-09-11 12:32:12

[ Watch the Video: Firestation To Investigate Thunderstorm Tops ] Lee Rannals for redOrbit.com - Your Universe Online 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. About 50 times a second bolts of lightning heat up the air to a temperature five times...

John P. Millis, PhD for redOrbit.com - Your Universe Online Little more than a century ago Austrian-American physicist Victor Hess established that out in the Universe charged particles are accelerated to very high energies, some eventually making their way to Earth. While much of the research into the curiously named cosmic rays – they, in fact, are not rays at all – has focused on determining their origins, scientists have also devoted considerable effort to studying their effects on...

Cosmic Rays Origins

[ Listen To The redOrbit.com Podcast: The Mystery Of The Origins Of Cosmic Rays ] John P. Millis, PhD for redOrbit.com - Your Universe Online Streaming across the Universe are high-energy charged particles, known as cosmic rays. They move through space, interacting with our galactic magnetic field, deflecting in every possible direction. Eventually these fast-moving particles may impact the Earth’s atmosphere. For more than 100 years astronomers have been aware of their existence,...

Mexico Observatory To Hunt For Gamma Rays In Known Universe
2013-08-22 07:35:15

April Flowers for redOrbit.com - Your Universe Online A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory is designed to study the origins of very high-energy cosmic rays and observe the most energetic objects in the known universe. The HAWC uses a unique detection technique that is different from the classical astronomical design of mirrors, lenses, and antennae, making the extraordinary observatory a significant boost...

Fermi Begins Extended Mission
2013-08-22 04:19:34

[ Watch the Video: Fermi at Five Years ] redOrbit Staff & Wire Reports - Your Universe Online 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. Fermi, which began the extended phase of its mission on August 11, has given astronomers an increasingly...

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...
