Fields and flows fire up cosmic accelerators

Every day, with little notice, the Earth is bombarded by energetic particles that shower its inhabitants in an invisible dusting of radiation, observed only by the random detector, or astronomer, or physicist duly noting ...

NASA Goddard lab works at extreme edge of cosmic ice

(Phys.org) —Behind locked doors, in a lab built like a bomb shelter, Perry Gerakines makes something ordinary yet truly alien: ice. This isn't the ice of snowflakes or ice cubes. No, this ice needs such intense cold and ...

Firefly Satellite to study lightning

Satellites are big. They cost a lot of money. At least that's the impression a couple of University of Maryland-College Park students had when they applied for an internship to help construct a satellite instrument with scientists ...

Refining a cosmic clock

Physicists will soon have a better measure of the age of our galaxy, thanks to experiments described in a trio of papers appearing in the journal Physical Review C.

Spotting accelerator-produced neutrinos in a cosmic haystack

Physicists have developed new tools to help tone down the cosmic "noise" when searching for signs of particles called neutrinos in detectors located near Earth's surface. This method combines data-sifting techniques with ...

A Super-Efficient Particle Accelerator

This image of data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope shows a part of the roughly circular supernova remnant known as RCW 86.

Centenary of cosmological constant lambda

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two papers recently published in EPJ H highlight its role in modern physics and cosmology. Although the term was first introduced ...
