Astrophysicist Takeshi Sakai believes large stars born in the stellar clusters 10,000 light-years away hold clues to the origins of life. But studying these faraway bodies is a difficult task.

But when exactly each stage of a star’s life cycle happens is where things get complicated. Depending on their mass, certain stars hit those points after a different number of years.

All stars are made up of dust and gas, also known as nebula, and the universe is filled with them. This is also the same process as how the universe came to be.
