Gamma-ray burst GRB 260623A was detected by NASA’s Fermi telescope morning at 12:56 UTC Tuesday, triggering a global ...

The most powerful events in the known universe—gamma-ray bursts (GRBs)—are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the ...

China's Einstein Probe has spotted a cosmic explosion from a mysterious source that's unlike anything seen before. The burst ...

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 lightning can be ...

On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray ...

In October 2022, several space-based detectors picked up a powerful gamma-ray burst so energetic that astronomers nicknamed it the BOAT (Brightest Of All Time). Now they’ve confirmed that the GRB came ...

A peculiar cosmic event, dubbed EP240305a, has baffled astronomers with its rapid X-ray fade and lingering radio signals. Detected by China's Einstein Probe, this transient phenomenon exhibits ...

Last February a team of astronomers reported detecting an afterglow from a mysterious event called a fast radio burst, which would pinpoint the precise position of the burst’s origin, a longstanding ...

Roughly a year ago, astronomers announced that they had observed an object that shouldn’t exist. Like a pulsar, it emitted regularly timed bursts of radio emissions. But unlike a pulsar, those bursts ...
