Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

This artist’s illustration, which shows a high-speed jet of material being launched from a source that is embedded in a very dusty galaxy, depicts GRB 250702B — the longest gamma-ray burst that ...

Researchers from the Yunnan Observatories of the Chinese Academy of Sciences have conducted a new study on the temporal evolution of the afterglow from gamma-ray burst GRB 240825A. The study offers ...

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and emit "x-rays and gamma rays (magenta)," according to NASA's Goddard Space ...

Artist's rendition of GRB 250702B's ultra-relativistic jet (moving at nearly the speed of light) escaping from its dusty, massive host galaxy. Astronomers at the University of North Carolina at Chapel ...

Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...
