Astronomers Decode Mysterious Blast From Space That Lasted Seven Hours
The signal lasted for seven hours, and its duration and intensity suggest previously unknown processes in the universe.

JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

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 ...

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.
