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.

We call this atomic reaction nuclear fusion. However, the …
Web7 de jul. de 2024 · A protostar is formed as gravity begins to pull the gases together into a ball. This process is known as accretion. As gravity pulls the gasses closer to the center of the ball, gravitational energy begins to heat them, causing the gasses to emit radiation. At first, the radiation simply escapes into space.
