Have you ever been interested in w hat is the life of a star? What happens to it, no its not gonna always be black holes! Well im here to tell you ^^!

FYI-Not very good drawing ^^

As you see above, that is the life of a star. Now here's the description!

(Star Formation)
This is the cluster of helium clustering together, also known as "interstellar mass"
Over time it gather's up and gravity causes it to crush together forming a core.

(Main Sequence)
Over time, more and more gas and matter is added to the planet! (wee for the planet )

(Red Giant or Super Giant)
Now your probably wondering what this is, well its a star. Over time its used up alot of matter, but soon gravity is pushing on it, and due to the gravity being a stronger factor, the planet uses up more resources causing it to die quicker, but as a factor, it grows super huge. Like our sun maybe soon.

--------------

Now from here, the dying star has 2 paths depends on the mass + gravity of it.
--------------
Higher Mass path

(Supernova)
Due to all the pressure, and mass that has been left there, it soon implodes causing a huge invert of energy! Soon it has a explosion causing massive desruction around it...
---Path after Super Nova---

Black Hole
If whats left of it has massive gravity, and massive pressure, it causes a implosion of energy and it becomes a singularity (small thing) and forms a hole in spach of which massive gravity pulls in anything nearby.

Neutron Star
If whats left of the star didnt have enough energy, it forms a neutron star which stays in space but will never form anything else.

(---------------------------------------------)
Lower Mass


Now if the thing had lower mass, it would follow a lonely path.

(White Dwarf)
A dim star in space which is on its way to death, in space it would be impossible to see cause its so dark but it has only one way to go. It soon follows its path to black dwarf.

(Black Dwarf-AKA DEAD STAR)

This is a star which poses no threat or use. It is just a object in space.
I hope this is interesting. I remembered this all from a while ago ^^

As a body is crushed into a smaller and smaller volume, the gravitational attraction increases, and hence the escape velocity gets bigger. Things have to be thrown harder and harder to escape. Eventually a point is reached when even light, which travels at 186 thousand miles a second, is not travelling fast enough to escape. At this point, nothing can get out as nothing can travel faster than light. This is a black hole.

They have a astronmy class at my school and i am thinkin about takin it only because this all sounds super cool ^^

All stars except the Sun appear to the human eye as shining points in the nighttime sky that twinkle because of the effect of the Earth's atmosphere. Interferometer telescopes are required in order to produce images of these objects. The Sun is also a star, but it is close enough to Earth to appear as a disk instead, and to provide daylight.

Stars are not spread uniformly across the universe, but are typically grouped into galaxies. A typical galaxy contains hundreds of billions of stars. The majority of stars are gravitationally bound to other stars, forming binary stars. Larger groups called star clusters also exist.

Astronomers estimate that there are at least 70 sextillion (7×1022) stars in the known universe [1]. That is 70 000 000 000 000 000 000 000, or 230 billion times as many as the 300 billion in our own Milky Way.

The nearest star to the Earth, apart from the Sun, is Proxima Centauri, which is 39.9 trillion kilometers, or 4.2 light years away (light from Proxima Centauri takes 4.2 years to reach Earth). Travelling at the orbit speed of the Space Shuttle (5 miles per second -- almost 30,000 kilometers per hour), it would take about 150,000 years to get there. Distances like this are typical inside galactic discs, where the Sun and Earth are located. Stars can be much closer to each other in the centres of galaxies and globular clusters, or much further apart in galactic halos.

Wow the picture,omg the crappest picture in the world no offence but i did not get what you were trying to put on the picture. It didnt mean the slightest to me, i did not get the picture at all but hey you explained it and it sounds cool.
