What is it like where star density is greater?

There are 8 star systems (counting binaries as a single star system) within a distance of 10 light years from us. That means that this region of space has a density of approximately one star every 465 cubic light years.



Aren't there other places in the galaxy that would be much much denser? What would that be like? Would the starlight illuminate planets all "night" long? Could life exist on planets further from their suns because of the additional radiation?



I guess the "best answer" I'm looking for could be either scientific and factual, or creative yet logical.What is it like where star density is greater?its not a question of "could life exist" its a question of did or does it exist. life adapts to problems so if it was ever there it probably could survive.What is it like where star density is greater?Very hot.
