All stars begin their life in a<br />
NEBULA.<br />
A nebula is a gigantic cloud of<br />
dust, gas, and plasma in<br />
space.<br />

the nebula, gravity will start<br />
to pull everything together<br />
into a PROTO<strong>STAR</strong>.<br />
A protostar is an infant<br />
star…the equivalent of a<br />
newborn baby.<br />
