How gamma-ray bursts (GRBs), the most powerful and spectacular explosions known in the universe since the Big Bang, fuel their high-energy radiations? What kind of physical reactions can trigger and ...

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 ...

Using telescopes on Earth and in space, researchers traced GRB 250702B to the constellation Scutum, near the dense, dusty plane of the Milky Way. A separate study led by Jonathan Carney of the ...
