A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

NASA astronomers recently spotted a burst of radiation that was quickly crowned the "BOAT": the brightest of all time. The source of the radiation, which NASA said "swept through the solar system" on ...

Physicists have identified new forms of γ-ray radiation created inside thunderclouds, and shown that levels of γ-ray production are much higher on Earth than previously thought. Scientists already ...

Hawai’i (KXAN) – The brightest gamma-ray burst in human history was recently detected, scientists with the American Astronomical Society (AAS) announced on Tuesday. Nicknamed the BOAT, Brightest of ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries ...

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. When you purchase through links on our site, we may earn an affiliate ...

A new study suggests that explosive events in space have the potential to temporarily switch off the natural shield that protects us from harmful solar radiation. By Katrina Miller On Oct. 9, 2022, ...

A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists. Gamma rays are the ...

Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...
