| Protostar,illustration. A protostar is a star in the process of formation. They are created when a globule a dusty and gaseous nebula condenses under gravity. The globule acts as a cocoon. Because of this,protostars are generally invisible to the universe at large,except at infrared wavelengths. Protostars may be flattened out by rapid rotation,and are probably surrounded by a vast disc of gas and dust,around which planets will one day form. | |
