Scientific surmise, based on analysis of massive data relating to
luminosity, color and temperature, and grading....


It is a scientific surmise that there is birth, life and death journey for

every star.

They live for more than 10 billion years.

In the prenalal stage, the star is called a nebula.that comprises

clouds of dust, hydrogen and helium.

Condensation leads to the formation of a developing pro-star.

It might take millions of years for stellar winds of gravitational

forces to gather and compress the massive clouds of hydrogen to

the point where its gravity is powerful enough to initiate nuclear

fusion that designates the space body "star"...
