NGC 1741
Distant pair of interacting galaxies in the constellation Eridanus
From Wikipedia, the free encyclopedia
NGC 1741 is a distant pair of interacting galaxies (NGC 1741A and NGC 1741B) in the Eridanus constellation.[3][4] It was discovered on 6 January 1878 by French astronomer Édouard Stephan.[5] As a result of the collision, the galaxies are in a rapid starburst phase.[6][4] The galaxies are classed as Wolf–Rayet galaxies due to their high content of rare Wolf–Rayet stars.[7]
