Facts About Stars!

Introduction

I will be writing a report of the different appearance, temperatures

and the life cycle of a star which is a hot ball of plasma.

The Life-Cycle of a Star

Gravitational forces pull a cloud of nebular together and the cloud spins into a disc shape. It spins for a few years as it gets faster and faster and faster until it forms a bright light in the middle, this is called a prototype star. As it continues to spin, suddenly a big bang with a blinding light occurs and there is a star. The life of a star is not very nice though, the gravitational forces that pulled it together will start to crush it, but the star burns helium (until it runs out that is) which creates the stage called the main sequence. The star burns helium to expand itself and fight against the gravity to equalise the pressure.

Types of Stars

The stars defy the laws of colour (just like fire). Red you would think is HOT, no it is the coolest type star, then there is yellow: medium, then green: hottish and last but not least blue the hottest. There are a few other complicated ones like E.g Yellow Gv2 Dwarf. Now the stages first type main sequence which is in the paragraph above, then giant super-giant which is when the have been around for a long time and has grown big, then dwarfs when the are running out of helium and are shrinking then finally a dead cold black ball.

Appearance

There is (listed in heat) Red, Yellow, Green and Blue stars. Here is a fact you probably wouldn't know: Did you know that stars don’t twinkle? Stars appear as small dots in the sky that twinkle, but they only look as if they twinkle is that while the light travels through the layers of our atmosphere and there are small pockets of air that mess up the straight line of light so your eyes interpret this as twinkling.

Conclusion

So now we know what it is like being a star and the different stages and types. Here is a fun fact: There are over 500 billion stars which leaves over 400 galaxies including our galaxy the Milky Way.
