This Hubble photograph shows star cluster Pismis 24, which lies at the heart of emission nebula NGC 6357. The stars are some of the most massive ever seen in our galaxy, each of which weighs at least 100 times the mass of our Sun. Astronomers originally thought it was two stars, each of which exceeded the theoretical limits on stellar size. Hubble discovered that it's actually three stars, bringing the reality back in line with theory.

It seems like every time we observe some supermassive star it gets resolved into a multiple star. It' looking like that 120 Solar mass limit might be real for the current state of the universe.

These are three 'really big' stars in close proximity. And they will be short lived. What happens when the first one to go supernova does so? Are the other two going with it? Probably not, globular clusters are packed tighter. Still, interesting.

Maybe they will all go supernova together, since they were probabl all born together, and share a common composition. Wouldn't that be cool?:cool:
