Life Cycle of Star

Front

What is the main sequence in the life cycle of a star?

Back

The main sequence is the stable phase of a star's life where it fuses hydrogen into helium in its core, producing energy and light.

What type of stars are considered the hottest?

Back

Blue stars are the hottest type of stars, with surface temperatures exceeding 30,000 degrees Celsius.

Front

What is a protostar?

Back

A protostar is an early stage in the formation of a star, where a nebula collapses under gravity and heats up, leading to the birth of a new star.

Front

Do all stars produce their own light?

Back

Front

Where are stars born?

Back

Stars are born in nebulae, which are large clouds of gas and dust in space.

Front

What happens during a supernova?

Back

A supernova is a powerful explosion that occurs at the end of a massive star's life cycle, resulting in the star's outer layers being expelled into space.

Front

What is a red giant?

Back

A red giant is a late stage in a star's life cycle, where it 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, leaving a hot, dense core.

Front

What is the role of gravity in star formation?

Back

Gravity causes the gas and dust in a nebula to collapse, leading to the formation of a protostar.

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages: nebula, protostar, main sequence, red giant or supergiant, and finally, white dwarf or supernova.
