There's a reasonable chance this is the brightest gamma-ray burst to hit Earth since human civilization began.' An extragalactic outburst whose light hurtled through the inner solar system last ...

The bright flash of gamma-ray light was first detected by NASA’s Neil Gehrels Swift Observatory on October 19, 2019. The explosion lasted just over a minute — considered long, like any gamma ...

On Dec. 11, 2021, several observatories and satellites recorded a very bright, 50-second gamma-ray burst and optical, infrared and X-ray emissions associated with the burst.

Such events are known as gamma ray bursts, and astronomers who have continued studying this one said it was the “brightest of all time.” Now, a team of scientists have discovered that this ...

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 ...

As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is ...

Languages: English. You can get in touch with Jess by emailing j.thomson@newsweek.com. A massive gamma-ray burst spotted by scientists last year is possibly the most powerful ever detected 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 ...

This implies that lightning is most likely a major instigator of gamma ray generation through supercharging already an electric field’s high energy electrons. But other recordings yielded ...
