Detailed explanation-1: -Solar Nebula. Our solar system began forming within a concentration of interstellar dust and hydrogen gas called a molecular cloud. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center. The remainder of the cloud formed a swirling disk called of the solar nebula.
Detailed explanation-2: -Nebulae are interstellar clouds of gas and dust. Many nebulae are formed from the remnants of dying stars. Nebulae are often also regions where new stars are born. Nowadays, the term ‘nebula’ refers to an interstellar cloud of dust and gas.
Detailed explanation-3: -The Local Interstellar Cloud is a “bubble” in interstellar space. The solar system has been moving through the cloud and a local region called “The Local Fluff” for tens of thousands of years. These caverns can be caused by the strong winds from young stars and stellar explosions called supernovae.
