A nebula is a gaseous region in space where new stars are born. In these regions, forces of gravity cause hydrogen and helium gas to increase in density. As the density of the gases increases the force of gravity attracts even more matter. When it gets large enough the pressure causes fusion to begin and atoms slam together. There you have it – a star is born!
However, new stars aren’t formed overnight! It takes hundreds of thousands or millions of years! When you look at nebulae such as Orion and Rosette through a telescope, you’re taking a peek at the newest stars around!
One small thing!
A planetary nebula is not the same. In fact, this is something that happens at the end of a star’s life. A planetary nebula is the gas ejected from a red giant star at the end of its life. No new stars here!
