VERSION|0.5.1|NAME|HarryR|DATE|1365067985|CONTENT|The APOD is about galaxy M64 that has an inner disc rotating one way and an outer disc that [i]rotates in the opposite direction[/i]. How&#039;s that work then? It says M64 is the result of 2 galaxies colliding 1 Bn years ago but that doesn&#039;t help me much. How would the collision end up producing this structure? Wouldn&#039;t the counter rotating bits keep bumping into each other slowing each other down?|IP-ADDRESS|80.153.30.244|MODERATIONFLAG|
