Peculiar galaxies of Arp 273.
These galaxies are located about 300 million light years away. The strange appearance is due to gravitational tides as the pair engage in close encounters. The center of these galaxies are separated by 100,000 light years.
These type of galaxies are actually very common in the universe. For example, our own galaxy is on a collision course with the Andromeda galaxy.
