NGC 3125 is a large starburst galaxy in the constellation Antlia. It is located approximately 50 million light-years away from Earth. Starburst galaxies are galaxies in which unusually high numbers of new stars are forming, springing to life within intensely hot clouds of gas.[2]

Morphology

NGC 3125 is notable as it displays large and violent bursts of star formation.[3] Some of these stars are notable; one of the most extreme Wolf–Rayet star clusters in the local Universe, NGC 3125-A1,[4] resides within NGC 3125.

Nearby galaxies

NGC 3125 is member of the LGG 189 Group, which also includes the galaxies NGC 3113, NGC 3137, and NGC 3175.[5]
