Unit 07 - Star Cycle (FZS)

Front

What is a nebula?

Back

A nebula is a cloud of gas and dust in space, often considered the birthplace of stars. It contracts due to gravity to begin forming a star.

Front

What type of star is responsible for forming elements in GREEN?

Back

Super Giant Star.

Front

What are main sequence stars?

Back

Main sequence stars are the majority of stars in the universe and are in the stage where they fuse Hydrogen into Helium.

Front

What can a core collapse after a supernova become?

Back

A neutron star or a Black Hole if massive enough.

Front

What conditions are required for the process of fusion?

Back

High heat and high pressure.

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages such as nebula, main sequence, red giant, supernova, and then either a neutron star or black hole.

Front

What happens to a star after it exhausts its hydrogen fuel?

Back

It expands into a red giant and may eventually shed its outer layers.

Front

What is a supernova?

Back

A supernova is a powerful explosion that occurs at the end of a star's life cycle, often resulting in the formation of a neutron star or black hole.

Front

What is a black hole?

Back

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is the difference between a white dwarf and a neutron star?

Back

A white dwarf is the remnant of a low to medium mass star, while a neutron star is the remnant of a massive star after a supernova.
