Front

What is a supernova?

Back

A supernova is the explosive death of a star, resulting in a bright burst of light and the ejection of its outer layers into space.

What occurs at stage 6 of a star's life cycle?

Back

At stage 6, a star has no more energy and only emits light from leftover star remnants after gas and dust are dispersed into space.

Front

What is the remains of a high mass star called?

Back

The remains of a high mass star can be a neutron star or a black hole, depending on the mass of the original star.

Back

A neutron star is the dense remnant of a high mass star that has undergone a supernova explosion.

Front

What happens to a star when it runs out of fuel?

Back

When a star runs out of fuel, it can no longer sustain nuclear fusion and will eventually collapse or explode.

Front

What is a black dwarf?

Back

A black dwarf is a theoretical stellar remnant that occurs when a white dwarf has cooled down and no longer emits significant heat or light.

Front

What is a white dwarf?

Back

A white dwarf is the hot, dense core left behind after a star has shed its outer layers and ceased nuclear fusion.
