Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. Gamma rays are high-energy photons produced by some of the most violent ...

Scientists warn that a gamma-ray burst (GRB)—one of the most powerful explosions in the universe—could severely damage Earth’s atmosphere, disrupting weather patterns, the ozone layer, and ...

Captain America: Brave New World is about to hit cinemas, bringing with it the gamma-ray-powered Red Hulk. Here's what you need to know about that high-energy radiation.

Gamma ray bursts are detected roughly once a month, Mereghetti says, but only three magnetar giant flares have been spotted from within the 100 billion stars within the Milky Way in the last 50 years.

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some ...

Early-time gamma-ray constraints on cosmic-ray acceleration in the core-collapse SN 2023ixf with the Fermi Large Area Telescope. Astronomy & Astrophysics , 2024; DOI: 10.1051/0004-6361/202349061 ...

The gamma-ray burst GRB 221009A trumped such previous explosions. Most instruments designed to detect this type of light couldn't handle the anomalously extreme radiation.

Gamma rays don’t directly affect people on Earth’s surface because the photons are absorbed by our atmosphere. But scientists are investigating if some of these very energetic rays could trace ...

We are also creating a table of the past gamma-ray bursts and the observations of the ozone layer and trying to see if they match,” he said. Nature Communications, 2023. DOI: 10.1038/s41467-023 ...

A World-Changing Gamma Ray Laser Is on the Horizon. It Could One Day Unlock Interstellar Travel Researchers are finally getting close to solving “one of the most important problems in physics.” ...

Once ionized, the molecule is unable to absorb any ultraviolet radiation, temporarily exposing Earth to more of the sun’s damaging rays. Gamma ray bursts have been known to ionize molecules at ...
