Detailed explanation-1: -As the nebula collapses, it heats up, spins faster, and flattens. The Sun formed in the very center of the nebula. We have observed disks around other stars. These could be new planetary systems in formation.
Detailed explanation-2: -The primary source of spin in nebulae (also for galaxies), is torque from the local environment. Nearby nebulae, clouds, stars, etc can exert a net torque on the nebula (or galaxy) giving it angular momentum. This is the primary source of spin for nebulae.
Detailed explanation-3: -Because of the competing forces associated with gravity, gas pressure, and rotation, the contracting nebula begins to flatten into a spinning flattened shape with a bulge at the center, as illustrated in the following figure.
