A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...

A single gamma-ray burst has forced astronomers to redraw their mental map of how the most violent explosions in the universe work. Instead of behaving like a textbook blast, this eruption stayed ...

A NASA-funded scientist has produced a new type of picture of the Earth from space, which complements the familiar image of our “blue marble”. This new picture is the first detailed image of our ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

Gamma-ray bursts (GRBs) are intense, transient cosmic events, typically originating from massive stellar collapses or mergers of compact objects, which serve as crucial probes for understanding the ...

Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion-year lifetime. These transient phenomena ...

An astounding gamma-ray burst, dubbed GRB 221009A, continues to amaze even though it has been more than a year since it was detected. Scientists from Italy have recently published a study that shows ...

When gamma rays hit molecules in the Earth’s atmosphere, they create a cascade of lower energy particles, and these can interact with the water molecules in those big tanks. Sensitive instruments keep ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...
