Cosmic gamma-ray source map unveils origins of high-energy particles

The galactic sources of nine extremely high-energy gamma rays have been identified by scientists from Penn State and members of the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. All of the sources generate gamma rays with powers more than 56 trillion…

The observed influence of gamma­-ray bursts on Earth’s magnetic field

The observed influence of gamma­-ray bursts on Earth’s magnetic field

Gamma Ray Bursts (GRBs) are the brightest explosions in the Universe. They are detected by orbiting space telescopes at the rate of about one a day. The number that could be detected from Earth should be much higher than the current rate, but the efficiency of the…

Study of gamma ray burst may change our understanding of how stars are formed

A group of researchers observing a specific gamma ray burst (GRB) have found that its probable host galaxy is almost entirely deficient in molecular gas. Molecular gas has long been considered to be the main raw material used in the formation of stars. The current…

Gamma ray burst stuns astronomers – Space News from Electric Universe

The most intense electromagnetic event known to occur in the heavens is the gamma-ray burst. For many years, scientists have claimed that most gamma ray burst occur when stars run out of nuclear fuel then collapse to form a black hole, neutron star or quark star.

Colliding neutron stars source of all the gold in universe

Colliding neutron stars source of all the gold in universe

Contrary to what most people think, it appears that gold did not form inside our planet eons ago. The reason for this conclusion is simple. Gold is heavy, and have it formed before Earth's crust solidified it would have sunk through the liquid
