Imagine the distance between the sun and the star nearest to it -- a star called Alpha Centauri. That's a distance of about four light years. Now, imagine as many as 10,000 of our suns crammed into that relatively small space. That is about the density of a galaxy that was recently discovered by an international team of astronomers led by a Michigan State University faculty member.
