How a protostar is formed
http://sunshine.chpc.utah.edu/Labs/StarLife/protostars.html WebHow and when a protostar is formed? Stars begin to form from clouds of gas in space. The cold temperatures and high densities (compared to elsewhere in space, but would be considered a vacuum on Earth) of these clouds allow gravity to overcome thermal pressure and start the gravitational collapse that will form a star.

Astronomers have struggled to understand how the largest stars — up to 120 times as massive as the Sun — can form by sucking in nearby matter. The problem is that, once a star reaches about 20 solar masses, the outward force of its intense radiation exceeds the gravitational force that pulls in matter.
