How Are Stars Born?

The creation of a star

Nebula Nursery

Stars are created from the ionized gases and dust found in nebulae- which makes them perfect for mothering star babies. Sometimes, the nebulae cannot resist the gravitational force and will collapse into a globe of gas. The globule will begin to spin, and pressure and temperature rise. The globule transitions into a disk with a central core; it has the potential to become a solar system.

What causes Gravitational Collapse?

All masses and bodies in space have their own gravity- when the force of the gravity pulling them closer to the center of their mass is greater than the internal pressure, it can collapse. Stable bodies, like our Earth and our Sun, have internal pressures that counterbalance their gravity (for now).
