  We obtain an exact simple solution of the Einstein equation describing a
spherically symmetric cosmological model without the big-bang or any other kind
of singularity. The matter content of the model is shear free isotropic fluid
with radial heat flux and it satisfies the weak and strong energy conditions.
It is pressure gradient combined with heat flux that prevents occurrence of
singularity. So far all known non-singular models have non-zero shear. This is
the first shear free non-singular model, which is also spherically symmetric.
