  We study the patterning and fluctuations of a collection of active
contractile polar filaments on a two dimensional substrate, using a continuum
description in the presence of athermal noise, parameterised by an active
temperature $T_A$. The steady states generically consist of arrays of inward
pointing asters and show a continuous transition from a moving aster street to
a stationary aster lattice. In contrast to its equilibrium counterpart, this
active crystal shows true long range order at low $T_A$. On increasing $T_A$,
the asters remodel with a distribution of lifetimes; concomitantly we find
novel phase transitions characterised by polar and bond-orientational order.
