Question

How are star form?Explain Briefly?

Answer 1

Star Formation

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. As the cloud collapses, the material at the center begins to heat up. Known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. Three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the Milky Way are paired or in groups of multiple stars.

Answer 2

Star starts with a cloud of gas mostly made up of hydrogen, the most plentiful substance in the universe. The cloud begins to collapse under the mutual gravitational attraction of all the gas molecules. As it collapses the gravitational attraction grows greater as more matter is concentrated, and it collapses still further. As this happens the temperature rises due to the increased pressure. At some point the pressure and temperature in the center (the core of the proto-star) grows so great that hydrogen fusion is ignited, where by hydrogen atoms fuse together to create helium, which releases
