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 ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

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 ...

The 10,000-year-old remnant of a supernova 2,600 light years away is acting like a giant particle accelerator, and it’s flinging cosmic rays out across the galaxy — like the Large Hadron Collider on ...

For decades, researchers assumed cosmic rays are flung into space from supernova. But new research suggests even supernovae are not strong enough to push particles to petaelectronvolts (PeVs). Instead ...

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 ...

While the San Francisco 49ers and the Baltimore Ravens were butting heads and other body parts a couple of Sundays ago, they were simultaneously taking a whole different type of pounding, though they ...
