STARS

Answering all your questions about them

A brief summary about stars

- Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies


-A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood

Unique Facts

- The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy


- When a star has fused all the hydrogen in its core, nuclear reactions cease


- In general, the larger a star, the shorter its life, although all but the most massive stars live for billions of years

WHO first discovered STARS

- There is actually no historic recording of who first discovered stars

- Some say it was the ancient Greeks and the Egyptians


What exactly are "Stars"

- Stars are cosmic energy that let off heat, energy, light and other different types of radiation

- They are composed largely of gas and plasma, a superheated state of matter composed of subatomic particles

-The most familiar star to many people would be the sun

-Stars are classified in a range from dwarfs to supergiants

WHY are STARS important to the galaxy

- With out stars, we wouldn't have a sun

- Stars are what create a galaxy without stars there wouldn't be one

- There really is no key importance to stars besides that, just gases and dust coming together through gravity making little kids happy because they now have something to wish upon

HOW are STARS created

-Stars form when giant gas clouds start to clump together and collapse in upon themselves. This clumping is often caused by energy waves from nearby exploding supernova

-As they collapse, the molecules that form the clouds compress in upon each other to form helium and hydrogen

-Once gravity pushes them together strongly enough, nuclear fission will begin to occur in the core of the star. This process will continue throughout the life of the star, until all of the fuel is used up.


WHERE are STARS located

-Most stars are located in the milky way

-stars are located in outer space of course

- The farthest stars found in the galaxies are billions of miles away

-closest star would be the sun

- The nearest star, besides the sun, is 40 million kilometres away
