  In these proceedings, we present recent results of $\Upsilon$ measurements in
heavy-ion collisions from the STAR experiment at RHIC. Nuclear modification
factors ($R_{AA}$) for $\Upsilon(1S)$ and $\Upsilon(1S+2S+3S)$ in U+U
collisions at \sqrtsNN\ = 193 GeV are measured through the di-electron channel
and compared to those in Au+Au collisions at \sqrtsNN\ = 200 GeV and Pb+Pb
collisions at \sqrtsNN\ = 2.76 TeV. The ratio between the $\Upsilon(2S+3S)$ and
$\Upsilon(1S)$ yields in Au+Au collisions at \sqrtsNN\ = 200 GeV is measured in
the di-muon channel and compared to those in p+p collisions and in Pb+Pb
collisions at \sqrtsNN\ = 2.76 TeV. Prospects for future $\Upsilon$
measurements with the STAR experiment are also discussed.
