Black Holes and Star Life Cycle

The video tutorial explores the life cycle of stars, starting with how mass influences a star's fate. It covers the formation of nebula clumps and main-sequence stars, followed by the development of Red Super Giants and luminous WR stars. The process of a supernova leading to the creation of a black hole is explained, along with the impact these phenomena have on surrounding planets.

What factor is crucial in determining the fate of a star?

• Its color

• Its mass

• Its distance from Earth

• Its temperature

What is the initial phase of a star's life cycle?

• Red Super Giant

• Black Hole

• Main-sequence

• Nebula clumps

During the main-sequence phase, how does the size of a star compare to the Sun?

• It is 7 times bigger than the Sun

• It is the same size as the Sun

• It is 10 times bigger than the Sun

• It is smaller than the Sun

What does a Red Super Giant transform into?

• A Nebula

• A Black Hole

• A Main-sequence star

• A luminous Wolf-Rayet star

What astronomical event can lead to the formation of a black hole?

• Nebula clumping

• Supernova

• Main-sequence phase

• Red Super Giant phase
