Andromeda: born out of a massive collision?

Andromeda: born out of a massive collision?

A study that shows that M 31 was created by a merger with another spiral galaxy. Link shows a model and allows you to explore. A second part of the study shows tha Magellanic galaxies may have formed from the tidal tail that was created when the galaxies were merging six billion years ago. I thought this is a very interesting study and was glad to find it. Enjoy! By the way, can you tell I'm under cloudy and snowy skies?
