  We present Galaxy Evolution Explorer (GALEX) images of the prototypical
edge-on starburst galaxies M82 and NGC253. Our initial analysis is restricted
to the complex of ultraviolet (UV) filaments in the starburst-driven outflows
in the galaxy halos. The UV luminosities in the halo are too high to be
provided by shock-heated or photoionized gas except perhaps in the brightest
filaments in M82, suggesting that most of the UV light is the stellar continuum
of the starburst scattered into our line of sight by dust in the outflow. This
interpretation agrees with previous results from optical imaging polarimetry in
M82. The morphology of the UV filaments in both galaxies shows a high degree of
spatial correlation with H-alpha and X-ray emission. This indicates that these
outflows contain cold gas and dust, some of which may be vented into the
intergalactic medium (IGM). UV light is seen in the ``H-alpha cap'' 11 kpc
North of M82. If this cap is a result of the wind fluid running into a
pre-existing gas cloud, the gas cloud contains dust and is not primordial in
nature but was probably stripped from M82 or M81. If starburst winds
efficiently expel dust into the IGM, this could have significant consequences
for the observation of cosmologically distant objects.
