How is a galaxy formed
WebFor example, one spiral galaxy passing another with a stronger gravitational pull could lose some of its material, become distorted, and morph into a new shape. Some, like gas-rich dwarf galaxies, may be new, formed by material pulled from such encounters. Or perhaps when galaxies collide, they create a larger, oddly shaped mashup.
