Take some cosmic dust and gas, then add billions and billions of planets and a whole lot of stars to the mix. Spice it all up with a handful of gravity to hold things together, and you get a galaxy. Shaken, not stirred. Some of those ingredients would get clumped together. The gases and dust would merge into stars. And stars would get packed together into globular clusters. Some of these clusters could count up to a million stars stuffed into an area 3.2 light-years across. To put that in perspective, the closest star to our Sun is about 4.37 light-years away.
Could a planet even exist where so many stars are so close together?
