NASA Detects Most Powerful Gamma-Ray Bursts Close To Earth
The signal originated from the direction of the constellation Sagitta, and travelled an estimated 1.9 billion years to reach Earth, NASA said.

Study Explains Blinking Gamma-Ray Bursts Using Falling Stardust, Unsteady Jets
Astrophysicists have developed the first 3D simulation of the entire evolution of a jet from its birth by a rotating black hole to its emission far from the collapsing star. Simulation explains that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the ...

Spectacular Gamma Radiation From Collapse Of Dying Star Could Change Understanding Of The Universe
Scientists have recorded a cosmic explosion of gamma radiation from a collapsing star that challenges the established theory of gamma-ray bursts. The scientists said that these explosions occur when a massive star abruptly detonates and turns into a black hole.

Astronomers Observe Most Distant Explosion in Universe That Took Place 10 Billion Years Ago
Astronomers have spotted one of the most powerful and oldest explosions that took place nearly 10 billion years ago. The explosion that has been named SGRB181123B occurred just 3.8 billion years after the Big Bang.

Gamma Ray Emission, Trillion Times More Energetic Than Light, Observed
In a cosmic first, researchers have observed the most powerful and luminous yet known energy release -- a trillion times more energetic than visible light -- in the brightest type of electromagnetic events known to occur in the universe called gamma-ray bursts (GRBs).

Scientists Detect Gravitational Waves From A New Kind Of Nova, Sparking A New Era In Astronomy
Some 130 million years ago, in a galaxy far away, the smoldering cores of two collapsed stars smashed into each other. The resulting explosion sent a burst of gamma rays streaming through space and rippled the very fabric of the universe.

Largest Feature in the Universe Discovered, 5 Billion Light Years Across
A ring of nine gamma ray bursts - and hence galaxies - were found with a diameter five billion light years across.

Astronomers Discover Largest Feature in the Universe
Astronomers have found what may be the largest feature in the known universe: a ring of nine gamma ray bursts - and hence galaxies - five billion light years across.
