No gamma-ray bursts from within our own galaxy, the [[Milky Way Galaxy|Milky Way]], have been observed,<ref name="set to go supernova">{{cite web|url=https://cosmosmagazine.com/space/milky-way-star-set-to-go-supernova|title=Milky Way star set to go supernova|author=Lauren Fuge|publisher=Cosmos|date=20 November 2018|access-date=7 April 2019}}</ref> and the question of whether one has ever occurred remains unresolved. In light of evolving understanding of gamma-ray bursts and their progenitors, the scientific literature records a growing number of local, past, and future GRB candidates. Long duration GRBs are related to superluminous supernovae, or hypernovae, and most [[luminous blue variable]]s (LBVs) and rapidly spinning [[Wolf–Rayet star]]s are thought to end their life cycles in core-collapse supernovae with an associated long-duration GRB. Knowledge of GRBs, however, is from metal-poor galaxies of [[history of the universe|former epochs of the universe's evolution]], and it is impossible to directly extrapolate to encompass more evolved galaxies and stellar environments with a higher [[metallicity]], such as the Milky Way.<ref>{{cite journal | pmid =  23630373 | doi=10.1098/rsta.2012.0237 | volume=371 | issue=1992 | title=Gamma-ray burst progenitors and the population of rotating Wolf-Rayet stars | journal=Philos Trans Royal Soc A | pages=20120237 | author=Vink JS|bibcode = 2013RSPTA.37120237V | year=2013 | doi-access=free }}</ref><ref>{{cite book|editor1=Mario Livio|editor2=Nino Panagia|editor3=Kailash Sahu|author1=Y-H.
