    We know a lot about our own Milky Way galaxy. Since we are embedded in it, we have a close-up view of it. We've measured the distribution of stars in space and the numbers of stars that have different masses. Up until now, it has been assumed that other galaxies have the same distribution of stars -? that is, the relative number of stars at each mass is the same with very massive stars being rarer than smaller stars. But new results show that some galaxies have even more extreme distributions.
