How are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. … Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses the material at the center begins to heat up.
