Abstract
Athena is a new numerical code for astrophysical MHD which preserves the divergence-free constraint exactly, conserves total energy, and works with nested and adaptive meshes. The current status of the code is summarized. Athena is being used for a number of applications, a selection of which are described here, including the magnetic Rayleigh-Taylor instability, MHD shock-cloud interaction, and the decay of supersonic MHD turbulence. Future applications and algorithm developments are summarized.
