Big Bang Theory is the most accepted theory regarding the origin of Universe. It is believed that a gigantic explosion formed small atoms which initiated the formation of the Universe. At that moment, all the matter of the universe were located at a single place from where they began their explosive expansion. In this way, first atoms were created and then molecules were formed out of atoms.Eventually a nebula was formed. The universe is still expanding.
A Nebula is a huge cloud floating in the Universe , is interstellar clouds of dust and gas.Thus, Nebulas are either remnants of matter from the original big bang or the result of stars either collapsing or going supernova( exploding to die). The temperature at the centre of nebula is very high because of collision of atoms and molecules at attracted by the gravity of each other. When the temperature rises above 10 million degree Celsius, nuclear chain reactions take place place and a new star is born. Thus, a nebula is a birth place of stars.( Nebula simply means cloud in Latin)
