About a trillion tiny particles called neutrinos pass through you every second. Created during the Big Bang, these “relic” neutrinos exist throughout the entire universe, but they can’t harm you. In ...

For the first time, scientists have been able to trace the origins of a ghostly subatomic particle that traveled 3.7 billion light-years to Earth. The tiny, high-energy cosmic particle is called a ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...

Searches for dark matter particles have come up empty so far, driving theorists to get more creative with their ideas.

The search for a hypothetical subatomic particle that could signal new physics just narrowed a bit — thanks to the light swirling around a gargantuan black hole in another galaxy. Now, the particulars ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. Physicists at the U.S. Department of Energy's (DOE ...

Ultra-high-energy particles from just outside enormous, active black holes in nearby galaxies travel as far as 250 million light years to make it all the way to Earth, an international team of 400 ...

Scientists have been searching for sources of cosmic rays for more than a century. Astronomers have traced a high-energy neutrino to its cosmic source for the first time ever, solving a century-old ...

This article addresses a common misunderstanding among some users regarding non-volumetric particle counters. Some users believe that dividing particle counts by the counting efficiency (CE) at the ...
