Space weather begins with an eruption such as a huge burst of light and radiation called a solar flare or a gigantic cloud of solar material called a coronal mass ejection. These bursts of plasma often travel toward Earth, where radioactive particles interact with the planet’s magnetic field and can disrupt the electric grid.

The space weather threat... and how we protect ourselves

The space weather threat... and how we protect ourselves

The Sun continually ejects high-energy electrons, protons, and other nuclei that bombard the Earth, producing space-weather effects such as the beautiful northern lights but also others that can destroy satellites and disrupt our lives here on Earth. 24 Apr, 2016

Picture of the Week: Making the (reactive) case for explosives science

A "reactive case" is a new concept in explosives science currently being tested at Los Alamos National Laboratory. A reactive case would do more than just contain an explosive, but rather become part of the explosive event itself, actually enhancing or boosting the explosion while decreasing far-field fragmentation damage. 16 Oct, 2015

In 2000, the U.S. and Russia committed to each "permanently dispose" of "no less than or at least" 34 metric tons of weapons-grade plutonium. The Department of Energy (DOE) announced a strategy for the permanent disposition of U.S. surplus weapons-grade plutonium: convert the energy stored in the nation's stockpile of surplus plutonium pits into electrical power for homes and businesses by burning it as fuel in domestic commercial nuclear reactors. 07 Aug, 2015
