When galaxies collide, some star systems are thrown into intergalactic space. What becomes of them?

Will they still function as a regular star system, or will they be affected in some way?When galaxies collide, some star systems are thrown into intergalactic space. What becomes of them?It depends on the specific gravitational effects on the specific systems, I would expect.



Some will probably carry on as if nothing happened, except they move farther and farther from the home galaxy (and the bow wave that protects them from the intergalactic medium) over time.



Others may be disrupted by the interactions of gravity. The planets in the system might get disrupted, some flung out of the system, others heaved into interstellar space. It all depends on the specifics of the interaction, which are devilishly hard to predict.When galaxies collide, some star systems are thrown into intergalactic space. What becomes of them?Yes, they will still function as a regular star system.When galaxies collide, some star systems are thrown into intergalactic space. What becomes of them?For the most part (there are exceptions), the evolution of stars is pretty much independant of their surroundings. Those stars that have been discharged from their parent galaxy by intergalactic collisions or, in some cases, by a close passage near the central super-massive black hole in many galaxies, will eventually find a new home in the larger galaxy that eventually evolves from the collision. There are undoubtedly many other stars that drift within intergalactic space. The Hubble Space Telescope discovered 600 or so such "outcast" stars in a small region in the Virgo cluster, 60 million light-years away from Earth.When galaxies collide, some star systems are thrown into intergalactic space.

Over millions of years, the nighttime skies of the planets in that system will grow darker as the system drifts further from the galaxy.



It could be considered a catastrophe if it meant there were no nearby planets for an advanced civilization to colonize. Then again, it could be considered a boon if it meant they escaped the effects of a nearby supernova.
