Astronomy Interview Question:

Do galaxies interact?

Submitted by: Administrator

Of course we have no direct evidence of galaxies interacting but it does appear that they can and do, and are at this very moment, interacting.

Usually a violent and energetic affair, galaxies interacting will cause much destruction of existing material and then result in a product phase of much star formation and activity as the repercussions are felt throughout the galaxy.
