re: life on ejected planets. - Ejected planets is one thing...

Ejected planets means nil as life is concerned, because such planets will be stripped of any atmosphere and heat of a mother star once they enounter interstellar space. On the other hand, if one or if a rocky planet is to circle a star in a globular cluster, that's an entirely different thing in that it might survive and even may harbor life.

I'm not refering to our satellite moons as those orbiting our gas giants, but those that may have escaped our solar system as suggested in this thread, which, I find highly unlikely... unless there's a galactic event such as us encountering another solar system or even another galaxy (collision).

There may be remnants of the beginnings of our solar system out there, but it may be in the form of decipitating gas (long gone or foregone) or some rocky/icy remnants... or something sailing aimlessly in the darkness of space or orbiting a star within a globular cluster.
