Front

What is a Neutron Star?

Back

A neutron star is the remnants of a supernova explosion, incredibly dense and composed mostly of neutrons.

What is the final stage of a low to medium mass star?

Back

The final stage of a low to medium mass star is a white dwarf.

What is the difference between a Red Giant and a Supergiant?

Back

A Red Giant is a large star that has expanded and cooled, while a Supergiant is even larger and more luminous, often leading to a supernova.
