Front

What is a white dwarf?

Back

A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and shed its outer layers.

Front

What is a black dwarf?

Back

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

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.
