In these proceedings, we present recent results of Υ measurements in heavy-ion collisions from the STAR experiment at RHIC. Nuclear modification factors (RAA) for Υ(1S) and Υ(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 Υ(2S+3S) and Υ(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 Υ measurements with the STAR experiment are also discussed.
