Life Cycle of Stars

What is a star?

A star is a big ball of gas and they are filled with gas or plasma depending on how big the star is. Stars of average size and temperature live the longest lives of any stars. The color of the star will end up showing how hot or cold the star is. The blushish stars are the hottest stars out of all the star. The reddish stars are the coolest star out of all the stars, however they are still very hot stars. The sun is considered a cool star, so imagine star many times hotter than the sun.

Birth of Stars

A nebula will form a star and the nebula is made out of dust and gas. A nearby star explosion or other force will cause the nebula to spin and move around. Then, the gases, rocks, and dust within the nebula pull itself together causing the nebula to release a huge amount of energy. Finally, the star begins to shine out of the nebula and depending on the matter in the nebula depends on how big the star will be. There are many different stars it could turn into, the basic on is a regular star all by itself. Another type of star it could turn into is a star cluster that form by stars binding together in large groups and they will not orbit each other. Binary stars are formed when two stars are formed in one nebula and they will end up rotating each other. The life span of a star depends on their mass and stars go through stages of life like people so. High-mass stars form fast and have a short life. They only last for only seven million years. Low-mass stars live for 10,000 billion years.

Death of Stars

When stars die, they will either burn down or explode into a supernova with a big release of energy. If they end up turning into a supernova, they are not done dying yet. Giant stars will collapse into a black hole. Big star become dense and highly magnetic called a Neutron star. Neutron stars spin a lot and there are two types of Neutron stars. Pulsar is one type of Neutron star that emits a beacon of light. The magnetar another type of Neutron star has a magnetic field over a trillion times stronger than the sun's magnetic field. Disturbances called star quakes crack the magnetar's crust. The difference between a pulsar and a magnetar is their power source. A pulsar gets their energy from their spin and a magnetar gets its energy from its magnetic field.
