The mass loss caused by the furious stellar winds sloughing off the outer layers of the star's atmosphere considerably shortens the remaining life of the star.  Eventually the Wolf-Rayet star will run out of fusible material and will end its life as a [[Supernova#Type_1b_and_Ic|type Ib supernova]].<ref name="nz">http://www.peripatus.gen.nz/astronomy/wolraysta.html</ref>

There are only around 230 Wolf-Rayet stars known in our own [[Milky Way|galaxy]], with a further 100 in the [[Large Magellanic Cloud]] and a dozen in the [[Small Magellanic Cloud]].  Of all of these, the best known is '''Gamma 2 Velorum''', a multiple star system of six stars of which at least one is a Wolf-Rayet star.  Gamma 2 Velorum is visible to the unaided eye in the skies below 40 degrees south latitude and is nicknamed "Spectral Gem of Southern Skies".
