A gamma-ray burst hitting Earth is a rare but potentially devastating cosmic event. China caves on 125% tariff for major US export after White House predicts Beijing can't keep up Deion Sanders ...

A mysterious gamma-ray burst has left scientists baffled, as it appears to be more powerful and unusual than anything detected before. Gamma-ray bursts are the most energetic explosions in the ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument ...

Researchers had observed two forms of thunderstorm gamma-ray emissions: relatively long-lived “glows” lasting hundreds of seconds, as well as intense, microsecond-scale bursts known as ...

Ten flights with the plane, NASA’s ER-2 aircraft, captured the shimmer of gamma-ray outbursts over a variety of timescales and intensities, suggesting that the emissions are more complex and ...

While the gamma ray laser (also known as a “graser”) is still conceptual, it’s considered one of the most important problems in physics. Invisible to our eyes, gamma rays burst from ...

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 ...

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 ...

'We found a much stronger signal, and in a different part of the sky, than the one we were looking for.' Astronomers have discovered an unexpected and unexplained feature outside our Milky Way ...

Scientists have announced the discovery of nearly 300 gamma ray pulsars. The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration ...

Dubbed the "brightest of all time," or the BOAT, a gamma-ray burst detected in 2022 continues to astound astronomers, revealing severe effects in Earth's atmosphere. When you purchase through ...
