Question 1:

What is the initial stage in the life cycle of a star?

Explanation: The initial stage in the life cycle of a star is the protostar stage, where a dense cloud of gas and dust begins to collapse under its own gravity.

Question 2:

Which process fuels a main sequence star?

Explanation: The main sequence star is fueled by nuclear fusion, where hydrogen nuclei combine to form helium, releasing a tremendous amount of energy.

Question 3:

Which type of star undergoes a supernova explosion at the end of its life?

Explanation: Massive stars, much larger than the Sun, undergo a supernova explosion at the end of their lives.

Question 4:

What is left behind after a high-mass star goes through a supernova explosion?

Explanation: After a high-mass star goes through a supernova explosion, it can leave behind a dense remnant known as a neutron star.

Question 5:

What is the final stage in the evolution of a low-mass star, like the Sun?

Explanation: The final stage in the evolution of a low-mass star, like the Sun, is the formation of a white dwarf, which gradually cools and fades over billions of years.
