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 be 4.5 billion years old find Saturn to be only 2.5 billion years old,” says Thomas Mattsson, manager of Sandia’s High-Energy-Density Physics Theory Group. Results from Sandia’s Z Machine provides hard [...]
