NIF experiments study how ‘starstuff’ is made

Jul. 5, 2016 -  
When the renowned cosmologist Carl Sagan declared that “we are made of starstuff,” he wasn’t speaking metaphorically. As Sagan said in the TV series “Cosmos,” many of the elements in our bodies - “the nitrogen in our DNA, the calcium in our teeth, the iron in our blood” - were forged in the...

Experiments shine light on exotic cosmic rays

May. 3, 2016 -  
The Earth is under constant bombardment by subatomic particles called cosmic rays, including some, known as ultra-high-energy cosmic rays, which pack much more punch than the world’s most powerful particle accelerators. Fortunately, Earth’s atmosphere protects us by dissipating most of that energy...
