GENERAL KNOWLEDGE

Detailed explanation-1: -Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. 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.

Detailed explanation-2: -Stars are born in nebulae, which are huge clouds of gas composed basically of Hydrogen and Helium (the most common elements in the Universe). There may be regions of the nebula with a higher concentration of gases.
