Close encounters between galaxies are a messy business - but so beautiful!! This striking NASA Hubble Space Telescope image, which shows what looks like the profile of a celestial bird, belies the fact that close encounters between galaxies are a messy business.

This interacting galaxy duo is collectively called Arp 142. The pair contains the disturbed, star-forming spiral galaxy NGC 2936, along with its elliptical companion, NGC 2937 at lower left.

Once part of a flat, spiral disk, the orbits of the galaxy's stars have become scrambled due to gravitational tidal interactions with the other galaxy. This warps the galaxy's orderly spiral, and interstellar gas is strewn out into giant tails like stretched taffy. #nasa #nasagoddard #hubble #space
