SOLAR SYSTEM

Detailed explanation-1: -Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.

Detailed explanation-2: -Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as “stellar nurseries” or “star-forming regions", collapse and form stars.

Detailed explanation-3: -A nebula is an interstellar cloud of dust and other ionized gases resulting from the explosion of a star. Nebulae are clouds made up mainly of hydrogen gas and dust particles.

Detailed explanation-4: -Interstellar Matter Over the lifetime of the galaxy, interstellar clouds eventually turn into stars, the diffuse clouds being the residue from the star formation process.
