The afterglow of the study's subject, GRB 260310A, was one of the brightest observed in a decade.

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 ...

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 ...

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 ...

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 ...

When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

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 ...

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 ...

At 8:56 AM ET on Tuesday, NASA's Fermi Gamma-ray Space Telescope automatically detected a new long-duration gamma-ray burst, designated GRB 260623A, during the sudden collapse of what is likely a star ...

Astronomers keep finding enormous rings of radio light in deep space that nothing in the textbooks can account for. Each is more than 50 times the width of the Milky Way, glows only at radio ...

Illustration showing the absorbance of electromagnetic waves by the Earth's atmosphere. Different frequencies of radiation are absorbed by different amounts, notably visible light and radio waves are ...

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement ...
