  Vastly different time and length scales are a common problem in numerical
simulations of astrophysical phenomena. Here, we present an approach to
numerical modeling of such objects on the example of Type Ia supernova
simulations. The evolution towards the explosion proceeds on much longer time
scales than the explosion process itself. The physical length scales relevant
in the explosion process cover 11 orders of magnitude and turbulent effects
dominate the physical mechanism. Despite these challenges, three-dimensional
simulations of Type Ia supernova explosions have recently become possible and
pave the way to a better understanding of these important astrophysical
objects.
