Facebook Tweet Email Link Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary death of a star, or when it is shredded by a black hole. The observation of repeating bursts has never occurred before, given that …

Earlier this year, astronomers watched a burst of high-energy light that kept roaring back for nearly a full day. Gamma-ray bursts (GRBs) are usually sorted into short and long events, and they generally last from milliseconds to a few minutes. In a new study, researchers describe a signal named GRB 250702B that fired three distinct times over a few hours, …

Astronomers have spotted a cosmic explosion of high-energy gamma-rays unlike any ever seen before. The gamma-ray burst (GRB) designated GRB 250702B set itself apart from other explosive bursts of gamma-rays by exploding several times in one day. That’s something difficult to explain, given GRBs are thought to arise from the catastrophic deaths of massive stars, with no known scenario currently …

NEW YORK — Astronomers have spotted the brightest fast radio burst yet coming from a nearby galaxy. Observations of this phenomenon, a powerful flash of radio waves that lasts only about one millisecond, could shed light on one of the most mysterious cosmic phenomena ever studied. Fast radio bursts, or FRBs, were first discovered in 2007, but their exact sources …

Astronomers have discovered what may be the brightest flash of radio waves ever seen and have tracked this fast radio burst (FRB) back to its source. This feat could revolutionize theories surrounding these mysterious and rapid blasts of radiation that, in mere milliseconds, can emit as much energy as the sun does in its entire lifetime. First spotted in 2007, …

Fast radio bursts (FRBs) last around a millisecond and in doing so encode otherwise unattainable information on the plasma which permeates our Universe, providing insights into magnetic fields and gas distributions. In a paper authored by Manisha Caleb from the University of Sydney, the team report upon the discovery of FRB 20240304B which lies at a redshift of 2.148 +/- …
