IRAS 14348-1447 known as PGC 52270,[2] are a pair of spiral galaxies located 1 billion light-years away in the constellation of Libra.[1][3][4] The galaxy IRAS 14348-1447NE,[5] is in the early process of merging with IRAS 14348-1447SW,[6] causing gravity to pull stars from both galaxies and forming tidal tails.[3] As the interaction takes place, molecular gas is swirled about and creating emission that is responsible for the galaxies' ultraluminous appearance.[3][7][8]
