Active galaxies flare and fade in Fermi telescope all-sky movie (w/Video)

The gamma-ray sky comes alive in a movie made from data acquired by NASA's Fermi Gamma-ray Space Telescope during its first three months of operations. Gamma rays from sources near and far turn the sky into a hypnotic froth. ...

The Case of the Missing Gamma-ray Bursts

Gamma-ray bursts are by far the brightest and most powerful explosions in the Universe, second only to the Big Bang itself. So it might seem a bit surprising that a group of them has gone missing.

First gamma-ray-only pulsar observation opens new window on stellar evolution

About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. This object, known as a pulsar, is the first one known to "blink" only in gamma rays, and was discovered by the Large ...

Self-organized, one-dimensional Pt nanowires on Ge(001)

Oguzhan Gurlu and a group of scientists from University of Twente, Netherlands report about formation of Pt nanowires on Ge (001). Pt atoms adsorbed onto Ge(001) surface form extremely well-ordered nanowire arrays by self-organization ...
