  Ultrarelativistic heavy-ion collisions provide a unique environment to study
the properties of strongly interacting matter. Dileptons, which are not
affected by the strong interactions, are an ideal penetrating probe. We present
the dielectron results for p+p and Au+Au collisions at $\sqrt{s_\mathrm{NN}}}$
=200 GeV, as measured by the STAR experiment. We discuss the prospects of
dilepton measurements with the near-future detector upgrades, and the recent
lower beam energy Au+Au measurements.
