The age of stars reveal the story of the collision between galaxies
Interacting galaxy pairs are spectacular events where normal galaxies approach and collide with each other under the influence of gravity, where their gaseous content loses angular momentum and funnels towards the centers of these merging systems in the process. This … Continued
