Question

Answer 1

Life Cycle of a Star. Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.

Answer 2

These are the thee stages of Star☆.

☆☆☆☆☆☆☆☆☆☆☆

Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity.

☆☆☆☆☆☆☆☆☆☆☆

Stage 2 - A region of condensing matter will begin to heat up and start to glow forming Protostars. If a protostar contains enough matter the central temperature reaches 15 million degrees centigrade.

☆☆☆☆☆☆☆☆☆☆☆

Stage 3 - At this temperature, nuclear reactions in which hydrogen fuses to form helium can start.
