  Using recent developments in the theory of globally defined expanding
compressible gases, we construct a class of global-in-time solutions to the
compressible 3-D Euler-Poisson system without any symmetry assumptions in both
the gravitational and the plasma case. Our allowed range of adiabatic indices
includes, but is not limited to all $\gamma$ of the form $\gamma=1+\frac1n$,
$n\in\mathbb N\setminus\{1\}$. The constructed solutions have initially small
densities and a compact support. As $t\to\infty$ the density scatters to zero
and the support grows at a linear rate in $t$.
