Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

Gamma-ray bursts are a relatively new field in space science. The first was discovered in the late 1960s, and in the nearly six decades since, there’s never been a discovery quite like this. It may ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated. The GRB was "unlike anything ever witnessed before," according to the ...

James Webb has spotted the most distant supernova ever seen, exploding just 730 million years after the Big Bang, offering ...

The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a ...

Osaka, Japan – Lightning is a phenomenon that has fascinated humanity since time immemorial, providing a stark example of the power and unpredictability of the natural world. Although the study of ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

They were first spotted in the late 1960s by satellites designed to ferret out secret thermonuclear tests by the Chinese and Soviets, but some of the bursts of high-energy gamma rays picked up by ...
