LH 95 is a modestly sized stellar nursery in the Large Magellanic Cloud orbiting the Milky Way. It is related to the HII-region LHA 120-N 64, 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.[1] Imaging using the Hubble Space Telescope, however, allowed the identification of more than 2,500 pre–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.[2]

The large sample of low-mass pre–main sequence stars, stars that are currently under formation, in LH 95 allows the construction of the first most complete Initial Mass Function of an extragalactic star forming cluster.[3] The Initial Mass Function of LH 95 does not seem to differ from that typical for our Galaxy.
