There are moments when I think that science exists purely to blow my puny human mind. Take galaxy NGC 4622, for example. For years now, astronomers have wondered about the fact that it seemed to be moving in reverse, spinning towards the direction of its spiral arms instead of away from them. Now a new analysis of…
