Front

What is a black hole?

Back

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

Front

What is a supernova?

Back

The explosive death of a high mass star, resulting in a brilliant burst of light and energy.

Front

What is a planetary nebula?

Back

A stage in the life cycle of a star where it sheds its outer layers, creating a glowing shell of gas around the core.

Front

What is a main sequence star?

Back

A stable star that is in the longest phase of its life cycle, where it fuses hydrogen into helium in its core.

Front

What happens during the main-sequence stage of a star?

Back

The star spends most of its life fusing hydrogen into helium at extremely high temperatures.

Front

What is a red giant?

Back

A late stage in the life cycle of a star where it expands and cools after exhausting hydrogen in its core.

Front

What is a supergiant?

Back

An extremely large star that has a mass significantly greater than that of the Sun and is in a late stage of stellar evolution.

Front

What is a white dwarf?

Back

The remnant core of a star that has exhausted its nuclear fuel and shed its outer layers, typically very dense and hot.

Front

What is a black dwarf?

Back

A theoretical stage of a white dwarf that has cooled down and no longer emits significant heat or light.

Front

What is a nebula?

Back

A giant cloud of gas and dust in space, often the birthplace of stars.
