However, star formation begins in dark, dense clouds.
[Music]
Within one vast dark cloud, gravity collapses thousands of individual dense clumps.
[Music]
The core of a massive dense clump will compress and heat until it forms a protostar.
[Music]
A protostar grows as a disk of gas and dust accretes onto it,
and some of the accreting material is ejected along twin opposing jets.

While the star finishes its formation, planets build up within the surrounding disk.
