Stars could have carried mysteries with them for our ancestors now science has blessed us with knowledge about them. Have you ever asked yourself what are these stars, anyway? How are they formed? How did they even get there in space? Well, I have tried to answer a few questions in this post.

6. NUCLEARFUSIONITISSTARS CONTAIN LOTS OF HYDROGEN ATOMS AND
THEY ACTIVELY COMBINE WITH OTHER
HYDROGEN ATOMS TO FORM HELIUM. NUCLEAR
FUSION PRODUCES AN IMMENSE AMOUNT OF
ENERGY AND THE PROCESS KEEPS THE STARS

23. HOWARESTAR
CLUSTERSFORMED?

24. - The interstellar gas clouds remain under
equilibrium until attaining Jean’s mass.
- Beyond that mass, the cloud collapses
on itself (bruh why?) because of the
internal gravitational pull (fine then).
- Molecular clouds of extreme density
collapse under gravity to form a cluster
of thousands of stars instantaneously
(star cluster! Geddit?)
