In the stone mass of the Great Pyramid, a corridor about 9 meters long was outlined not by drills or demolition, but by particles raining down from space. Later confirmed with radar, ultrasound, and ...

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep off the coast of Sicily by the KM3NeT/ARCA neutrino telescope, the neutrino ...

For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo ...

When electronics meet cosmic rays, bad things can happen. Chip makers need to test what their products can withstand, and ...

The reason photographic darkrooms are needed is because almost any amount of light can ruin the film or the photographic paper before they are fixed. Until then these things are generally kept in ...
