Astronomy Photo of the Day: 04/09/14 – Arp 142
This pair of gravitationally interacting galaxies, known as Arp 142, is located some 326 million light-years from Earth in the southern constellation of Hydra.
The galaxy located in the upper portion of the pair is a spiral galaxy, known separately as NGC 2936. While NGC 2937, the galaxy located in the lower left of the image, is an elliptical galaxy. As you can clearly see, the gravitational perturbations have caused the gas and dust formations to scatter about, twisting them into tidal tails of material.
