NGC 1532 est une galaxie spirale de taille équivalente à la Voie Lactée, située à environ 50 millions d'années-lumière dans la constellation de l'Eridan, en interaction gravitationnelle avec ses galaxies satellites, et notamment NGC 1531.
La conséquence de ces interactions est une déformation spectaculaire des bras spiraux de NGC 1532, la création de "courants" de matière d'une galaxie à l'autre, et une flambée de formation d'étoiles.

NGC1532 is a spiral galaxy with a similar size to our Milky Way, located about 50 million LY away in Eridanus.
NGC1532 is in gravitational interaction with its dwarfs companions, specialy with NGC 1531.
These interactions lead to a spectacular distortion of the spiral arms of NGC 1532, the creation of unusual plumes above its disk, and have triggered starbust formation.
