Sentences with phrase «colliding galaxies»
The phrase "colliding galaxies" refers to two or more galaxies crashing into each other in space. It means that these giant clusters of stars and other celestial objects are coming together and their gravitational forces cause them to merge or interact in various ways. Full definition
