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...

Astronomers Predict 90 Percent Chance of Spotting an Exploding Black Hole in Next Decade
Astronomers now predict a 90% chance of detecting an exploding primordial black hole within a decade. Such an event would confirm Stephen Hawking’s theory that black holes evaporate, releasing a flash of radiation and exotic particles. Detecting one would revolutionize physics and rewrite our understanding of the universe.

NASA’s Hubble Space Telescope Tracks a Neutron Star With Mysterious Origin
NASA’s Hubble Space Telescope spotted a rogue magnetar, dubbed SGR 0501+4516, traversing our galaxy for a significantly long time. As per claims by scientists, it was first discovered in the year 2008 by NASA's Swift Observatory as intense flashes of gamma rays in the outer area of the Milky Way

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.
