Gamma-ray bursts are thought to be the most powerful, energetic events in the Universe. They can release as much energy in one second as an entire galaxy expels in an entire year.

Gold Created By Colliding Stars

A gamma-ray burst (GRB) created by the collision of two neutron stars has given researchers new insight into how gold, one of the rarest elements on Earth and in the entire universe, is formed.

Liverpool Telescope Successor In The Works

Stars sustain themselves by fusing elements in their core, producing even heavier atoms, releasing energy that keeps the immense force of gravity at bay. But eventually, the fusion process will no longer produce enough outward radiation pressure to sustain the star, and it will begin to collapse in on itself.

Dark Lightning And Visible Lightning May Be Connected
2013-04-25 11:02:17

New research from an international team of scientists has found that the mysterious phenomenon known as dark lightning may be connected to visible lightning.

Scientists Unravel The Mysteries Of Large Gamma-Ray Bursts

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,...
