In a breathless press release, NASA emphasized that their detectors all over the planet picked up on this, including NASA's Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory ...

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 ...

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 ...

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of ...

Yet they’ve never been able to pinpoint the source of any so-called terrestrial gamma ray flashes, says Yuuki Wada, an atmospheric physicist at the University of Osaka in Japan. He and his team ...
