30 Doradus has at its centre the star cluster [[NGC 2070]] which includes the compact concentration of [[Star|stars]] known as [[R136]]<ref name="Massey">{{Cite journal | bibcode = 1998ApJ...493..180M | title = Star Formation in R136: A Cluster of O3 Stars Revealed by Hubble Space Telescope Spectroscopy | date = January 1998 | journal = The Astrophysical Journal | volume = 493 | issue = 1 | pages = 180 | doi = 10.1086/305126 | author = Massey, P | author2 = Hunter, D. | s2cid = 122670111 | doi-access = free }}</ref> that produces most of the energy that makes the nebula visible. The estimated mass of the cluster is 450,000 [[solar mass]]es, suggesting it will likely become a [[globular cluster]] in the future.<ref>{{cite journal | last=Bosch | first=Guillermo |author2=Terlevich, Elena|author2-link=Elena Terlevich |author3=Terlevich, Roberto  | title=Gemini/GMOS Search for Massive Binaries in the Ionizing Cluster of 30 Dor | journal=Astronomical Journal | volume=137 |issue=2 | pages=3437–3441 | year=2009 | bibcode=2009AJ....137.3437B | doi= 10.1088/0004-6256/137/2/3437|arxiv = 0811.4748 | s2cid=17976455 }}</ref>  In addition to NGC 2070, the Tarantula Nebula contains several other [[star cluster]]s including the much older [[Hodge 301]].
