LH 95 is a modestly sizedstellar nursery in theLarge Magellanic Cloud. It is related to theHII-regionLHA 120-N 55, that is, a region of hydrogen ionized by the bright stars of LH 95.

Previously only young bright stars were known in this stellar association.[2] Imaging using theHubble Space Telescope, however, allowed the identification of more than 2,500pre–main sequence stars with masses down to about 0.3 solar masses, thereby giving a detailed picture of what a typical stellar association in the LMC looks like.[3]

The large sample of low-masspre–main sequence stars, stars that are currently under formation, in LH 95 allows the construction of the first most completeInitial Mass Function of an extragalactic star forming cluster.[4] TheInitial Mass Function of LH 95 does not seem to differ from that typical for the Milky Way.
