How does a star live its life?
Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.
What are the 5 stages of a stars life?
The formation and life cycle of stars
- A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula.
- Protostar. As the mass falls together it gets hot.
- Main sequence star.
- Red giant star.
- White dwarf.
- Supernova.
- Neutron star or black hole.
Do stars have their own life?
The life cycle of a star spans billions of years. As a general rule, the more massive the star, the shorter its life span. Birth takes place inside hydrogen-based dust clouds called nebulae.
What are the life cycle of a star?
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
What are the 7 parts of star?
Seven Main Stages of a Star
- Giant Gas Cloud. A star originates from a large cloud of gas.
- Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced.
- T-Tauri Phase.
- Main Sequence.
- Red Giant.
- The Fusion of Heavier Elements.
- Supernovae and Planetary Nebulae.
What happens in the life cycle of a star?
Life Cycle of a Star. Credit: NASA. Eventually, however, the hydrogen fuel that powers the nuclear reactions within stars will begin to run out, and they will enter the final phases of their lifetime. Over time, they will expand, cool and change colour to become red giants.
How is a star formed?
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.
What do we really know about stars?
After years and years of research, scientists have managed to find out quite a bit about the oh-so-secretive stars without losing a staring contest. Firstly, stars go through the same process that we do in the sense that they are born, live, and then die.
What is the average lifespan of a star?
The largest stars have the shortest lives, and can last a few billion, and even just a few million years. Over the course of its life, a star is converting hydrogen into helium at its core. This helium builds up and the hydrogen fuel runs out.
