Life Cycle of a Star

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages such as nebula, fusion stage, red giant, white dwarf, and black dwarf.

Front

What is a nebula?

Back

A nebula is a giant cloud of dust and gas in space, where stars are born.

Front

What elements primarily make up the sun?

Back

The sun is primarily made up of hydrogen and helium.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What happens during the red giant phase?

Back

During the red giant phase, a star expands and cools after exhausting its hydrogen fuel.

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 black hole?

Back

A black hole is an object with a gravitational pull so strong that nothing, not even light, can escape from it.

Front

What role does gravity play in star formation?

Back

Gravity causes dust and gas in a nebula to clump together, leading to the formation of stars.

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.
