A detector that was designed to probe dark matter has seen an elusive nuclear decay called two-neutrino double electron capture—with implications for nuclear and particle physics.
When the Homestake mine closed in 2003 after producing 42 million ounces of gold, it left a colorful gold rush history, tall steel headframes looming over a town of 3000 people, and an enormous hole in the ground: North America's largest and deepest underground mine.
On April 28, 1947 Stanford Linear Electron Accelerator Project Report No. 7 announced the realization of a dream 15 years in the making: the linear acceleration of electrons.
How do you make the invisible visible? Astrophysicists face this challenge daily. Unlike astronomers who view stars through telescopes, astrophysicists study cosmic particles that are too small or dark to see directly.
Some of Fermilab's mechanical technicians spend a lot of time underground. In the echoing tunnels of the Tevatron collider they fix things, crawling behind equipment to replace aging nuts and bolts and repair everything from vacuum pumps to multi-ton superconducting magnets.
Since its launch in June 2008, the Fermi Gamma-ray Space Telescope has shed light on some of the brightest, most explosive events in the universe and opened tantalizing windows into dark matter and the nature of space-time.
Long after the hard shaking stops, an earthquake's seismic waves reverberate around the world, imperceptibly rocking the ground. As one seismologist puts it, a great earthquake causes every grain of sand on Earth to dance.
