TOP: A huge star-forming region is rotating globally (white arrow). This large region can make multiple stellar systems. MIDDLE: Three protostars form deep in the collapsing cloud. The collapse causes eddies, allowing newly-forming stars to rotate in different directions and at different speeds (see arrows). BOTTOM: One protostellar cloud collapses further into a disk-like structure that rotates counter-clockwise (white arrows) about the newly-formed protostar. The protostar siphons material from a passing protostellar cloud rotating in the opposite direction, causing the outer part of the disk to rotate clockwise (yellow arrows). Eventually, planets will form, with the outer planets orbiting the star in the opposite direction from the inner planets.
