Latest Compton Gamma Ray Observatory Stories
Just over a month after launch, the Orbiting Carbon Observatory-2 -- NASA's first spacecraft dedicated to studying atmospheric carbon dioxide -- has maneuvered into its final operating orbit and produced its first science data, confirming the health of its science instrument.
For the first time ever, scientists using the Atacama Large Millimeter/submillimeter Array have discovered molecular gas in galaxies that had once been rocked by gamma ray bursts, according to new research published Wednesday in the journal Nature.
The event will serve as SwitchRay’s official launch to showcase their full suite of VoIP and Class 4/5 solutions. Mission Viejo, CA (PRWEB) March 13, 2014
Pamela Fleming, Executive Secretary of the Institute for Basic Research, Florida, announces the apparent detection of antimatter galaxies, antimatter asteroids and antimatter cosmic rays by the
The second year of an unprecedented balloon campaign in Antarctica has just begun.
Extremely quick, extremely bright radio pulses known as “fast radio bursts” may originate from flaring stars located within our own galaxy, researchers from the Harvard-Smithsonian Center for Astrophysics claim in a new study.
A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team of astronomers from Britain, Slovenia and Italy has glimpsed the infrastructure of a burst's high-speed jet.
NASA is preparing to launch an inexpensive, football-sized probe to study lightning, including its effects on the atmosphere and the possible link between the phenomenon and powerful energy bursts known as terrestrial gamma ray flashes.
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.
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,...
