Front

What is a Black Hole?

Back

A region in space with a gravitational pull so strong that nothing, not even light, can escape from it.

Front

What is a Nebula?

Back

A cloud of dust and gas in space, held together by gravity, where stars are born.

What is the life cycle of an average-sized star?

Back

Nebula > Protostar > Main-sequence star > Red giant > Planetary nebula > White dwarf > Black dwarf.

Front

What is a Black Dwarf?

Back

The final stage of a low-mass star's life, where it has stopped glowing and is a dark piece of space rock.

Front

What is a Supernova?

Back

The explosive stage in a high-mass star's life when it collapses and then explodes outward.

Front

What is a Protostar?

Back

An early stage in the formation of a star, where a cloud of gas and dust begins to collapse under gravity.

Front

What is a Main-sequence star?

Back

A stable phase in a star's life where it fuses hydrogen into helium in its core.

Front

What is a Red Giant?

Back

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

Front

What is a Planetary Nebula?

Back

A shell of gas ejected from a low-mass star during the later stages of its life.

Front

What is a Neutron Star?

Back

A very dense star composed mostly of neutrons, formed from the remnants of a supernova.
