Detection by Askaryan Radio Array holds promise for future research into sources, nature of cosmic rays and neutrinos ...

A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen ...

Astronomers have detected a lingering radio signal from a massive stellar explosion, offering evidence of how gamma-ray bursts behave when their jets point away from Earth. The event, designated GRB ...

There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed.

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 a millisecond, could ...

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 ...
