“And a supernova is described as "the most intense brilliance nature ever creates," ignoring the far brighter outbursts of quasars and the phenomenal stellar explosions known as gamma-ray bursters.”
“Greg Benford's "Penumbra" imagines a near wipe-out by a gamma-ray burst—a scenario we know could happen.”
“Take a look at the video and photos below to see depictions of terrestrial gamma-ray flashes in action, as observed by Fermi, and visit the NASA Fermi mission page to learn more about this discovery.”
“According to New Scientist, thunderstorms are known to shoot out terrestrial gamma-ray flashes TGFs, which Fermi observed in several instances.”
“The universe has big explosions all the time, novas and supernovas and gamma-ray bursts that are trillions of times more powerful than atomic bombs.”
“Sitting high above the Earth, the Fermi spacecraft has been keeping watch for gamma-ray flashes the highest energy form of light since 2008, and has detected 130 such flashes, all associated with thunderstorms.”
“Consequently most of the gamma-ray flashes that Fermi detected came from thunderstorms immediately below the spacecraft.”
“Around 500 gamma-ray flashes are thought to blast out from thunderstorms on Earth every day, but since most pulses last less than one millisecond, few of them are detected.”
“An international team of astronomers last week detected the most distant gamma-ray burst ever recorded, light that was emitted when the universe was less than 5 percent of its present age.”
“Customs Service in February 2003 to the Chenega Technology Services Corp. The work is to maintain thousands of gamma-ray, X-ray and other scanning machines at the nation's ports and borders.”
