That means the Milky Way could well turn out to be the missing link in a long quest to answer one of science's biggest questions: Are there fundamentally different types of galaxies, as it appears, or do most galaxies merely look different because we're catching them at different stages of a single, common life cycle?

Ellipticals are the most common type of galaxy and lack the spiral structure of disks like the Milky Way we call home.

Astronomers now know that it is NOT an evolutionary sequence because each type of galaxy has very old stars.

But, perhaps the situation is reversed: the type of galaxy determines the rate of star formation.
