Sandia’s Z machine helps solve Saturn’s 2-billion-year age gap
June 26, 2015 • Research supports 80-year-old prediction ALBUQUERQUE, N.M. — Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a two-billion-year discrepancy for computer models estimating Saturn’s age. “Models that correctly predict Jupiter to...

Iron rain fell on early Earth, new Z machine data supports
March 18, 2015 • ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories’ Z machine have helped untangle a long-standing mystery of astrophysics: why iron is found spattered throughout Earth’s mantle, the roughly 2,000-mile thick region between Earth’s core and its crust. At first blush, it seemed more reasonable that iron arriving from collisions between...

‘Iron Sun’ is not a rock band, but a key to how stars transmit energy
January 6, 2015 • ALBUQUERQUE, N.M — Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative...

Study rebuts hypothesis that comet attacks ended 13,000-year-old Clovis culture
January 30, 2013 • ALBUQUERQUE, N.M. — Rebutting a speculative hypothesis that comet explosions changed Earth’s climate sufficiently to end the Clovis culture in North America about 13,000 years ago, Sandia lead author Mark Boslough and researchers from 14 academic institutions assert that other explanations must be found for the apparent disappearance. “There’s no...

Sandia experiments may force revision of astrophysical models of the universe
March 15, 2012 •  ALBUQUERQUE, N.M. — The idea of compressing water is foreign to our daily experience. Nevertheless, an accurate estimate of water’s shrinking volume under the huge gravitational pressures of  large planets is essential to astrophysicists trying to model the evolution of the universe. They need to assume how much space is...
