Arp 143 (color)

Color version. Not sure I'm happy with it. Always looks weird when ground-based data are used to colorize HST data.

 

Copy-pasta from grayscale image description:

Well, it's been a while since I did a Prop15446 galaxy. This one was PI Julianne Dalcanton's favorite, so of course I had to. Featured are two interacting galaxies, one clearly full of star formation and dust with the other one smooth and not apparently doing much beyond participating in the interaction. The clumpy, dusty star-forming galaxy, perhaps once a spiral, now visibly being pulled into the smooth galaxy.
