Forms of Light Seeing Through Smoke. When you think about gargantuan phenomena such as the collision of galaxies, it might be tempting to imagine it as some sort of cosmic cataclysm, with stars crashing and exploding, and destruction on an epic scale. The calculations indicate that IC is swinging past NGC in a counterclockwise direction, having made its closest approach 40 million years ago. They constructed highly detailed models of galactic collision scenarios and ran them on supercomputers. Feedback from Massive Stars: Movies.
