  In this proceedings, we report the latest results of J/psi and Upsilon
production from the STAR experiment at RHIC, in different colliding systems and
colliding energies. J/psi nuclear modification factors (R_{AA}) in Au+Au
collisions at 200, 62.4 and 39 GeV and in U+U collisions at 193 GeV, Upsilon
R_{AA} in d+Au and Au+Au collisions at 200 and in U+U collisions at 193 GeV are
shown and compared to different theoretical models. We also present prospects
of quarkonium measurements at STAR.
