Origin Of Gamma Ray Flare Far Away From Their Galaxy’s Black Hole
2013-01-08 13:18:26

redOrbit Staff & Wire Reports - Your Universe Online 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, NASA officials announced on Monday. Using data collected by both the Fermi Gamma-ray Space Telescope and the National Science Foundation's Very Long Baseline Array (VLBA), astronomers at the U.S. space agency have discovered that the...

Students from across Europe have been selected as the winners of the ESA´s ℠Explore the high-energy Universe´ competition. Secondary school students were invited to choose from four projects relating to ESA´s Integral gamma-ray observatory in which they were challenged to Observe, Research, Design, or Build. To participate, students took on the roles of engineers, scientists, and astronomers to explore the extreme and ever-changing high-energy Universe, including...

Fermi Eyes 'Crazy-energetic Photons'
2012-03-19 03:40:04

[ Watch the Video ] The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot shake their fascination with the invisible. Outside the realm of human vision is an entire electromagnetic spectrum of wonders. Each type of light--­from radio waves to gamma-rays--reveals something unique about the universe. Some wavelengths are best for studying black...

Fermi Reveals Gamma-ray Bursts' Highest Power Side
2012-02-20 03:58:19

Detectable for only a few seconds but possessing enormous energy, gamma-ray bursts are difficult to capture because their energy does not penetrate the Earth's atmosphere. Now, thanks to an orbiting telescope, astrophysicists are filling in the unknowns surrounding these bursts and uncovering new questions. The Fermi Gamma-Ray Space Telescope, formerly called the Gamma-Ray Large Area Space Telescope, launched on June 11, 2008. As part of its mission, the telescope records any gamma-ray...

Firestation In Space To Open Firehose Of Lightning Data
2011-10-18 09:49:22

When opportunity knocked, NASA heliophysicist Doug Rowland answered. He and his team recently secured another flight opportunity for a pint-sized instrument studying lightning in Earth's upper atmosphere and now are bracing for a veritable "fire hose" of data about a little-understood phenomenon first discovered by scientists nearly two decades ago. The instrument, Firestation, is one of four experiments manifested to fly on an experiment pallet the U.S. Department of Defense plans to...

  Ray more than a thousand billion times brighter than the sun The brightest gamma ray beam ever created- more than a thousand billion times more brilliant than the sun- has been produced in research led at the University of Strathclyde- and could open up new possibilities for medicine. Physicists have discovered that ultra-short duration laser pulses can interact with ionized gas to give off beams that are so intense they can pass through 20 cm of lead and would take 1.5 m of...

Image 1 - Balloon-based Experiment To Measure Distant Gamma Rays
2011-09-18 05:04:59

  Beginning Sunday, September 18, 2011 at NASA's launch facility in Fort Sumner, New Mexico, space scientists from the University of New Hampshire will attempt to send a balloon up to 130,000 feet with a one-ton instrument payload to measure gamma rays from the Crab Pulsar, the remains of a supernova explosion that lies 6,500 light years from Earth. The launch is highly dependent on weather and wind conditions, and the launch window closes at the end of next week. The Gamma Ray...

ESA's Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum "Ëœgraininess' of space must be at much smaller scales than previously predicted. Einstein's General Theory of Relativity describes the properties of gravity and assumes that space is a smooth, continuous fabric. Yet quantum theory suggests that space should be grainy at the smallest scales, like sand on a...

Atlantis launched from Kennedy Space center on April 5, 1991 at 9:22 AM EST and landed at Edwards Air Force Base on April 11 at 6:55 AM EST. The shuttle orbited 93 times at an altitude of 248 nautical miles at an inclination of 28.45 degrees and travelled 2.5 million miles. The mission lasted 5 days, 23 hours, 32 minutes, and 44 seconds. The first spacewalk since 1985 was performed by two astronauts to test the ability to move themselves and equipment about while working on the planned...

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...

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
