Question

How do stars form from the remains of supernova?

Answer 1

Accumulating cosmic dust by gravity.

Explanation:

Supernovae can be the result of various conditions such as a great star exceeding Chandrasekhar Limit or a collapsed red giant whose nucleus transformed into a white dwarf which creates a supernova after having 'absorbed' excessive cosmic gas.

A massive explosion occurs... causing cosmic material and much energy to be scattered rapidly in an extensive ratio.

These components (together as a nebula ) are now heralds of many possible new-born stars.

Following Newton's Law of Universal Gravitation , this cosmic dust revolves for millions of years as it is attracted to itself.

Eventually, cumulative masses are gathering, making density and pressure higher until it forms a stellar body ...
