By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a ...

Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA explains. Credit: NASA Goddard Space Flight Center ...

Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an ...

NASA’s James Webb Space Telescope reveals new clues about a mysterious cosmic explosion that defies expectations. Researchers are investigating an unusual event in deep space that has left scientists ...

The approach focuses on improving the material properties of the mortar so that it can perform both as a structural component ...

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from Earth.

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...
