1. What do you know about stars? stars on not fire it is really plasma (faster molecule speed then fire)

2. How are stars different? stars a classed by size and age

3. How do stars form? that one i dont know *tear*

4. How do stars change? they age some die out and some implod and become black holes

5. What star patterns have you observed? never was good at it but i can always find big dipper and little dipper

6. How are stars grouped in the universe?when a group of stars group together it is called a galaxy

random fact the nearest galxy is Andromeda

i wanted to be an Astronomer when i was youger back in the days before i found out i was dumb

1. What do you know about stars?

I think stars are magical? [yes..i know they don't have magic] because we wish on them..and hope they come true...they give hope...to those who are hopeless...they are symbols of friendship and love and etc. I don't know...they have this aura that every time you look at them you feel relaxed...[that's what i think i don't know with other people..^__^]

2. How are stars different?

They are different coz they're unique...stars differ from each other with they're size, age, appearance, color, heat...they're like people..each person is unique and is a STAR!!!

3. How do stars form?

uhmmm..one tough question[for me].uh-Oh..i totally forgot...sorry...but i think they form when a star dies? dunno...lol.

4. How do stars change?

They are like people..that mature as they grow older...stars...on the other hand..when they get older they change color...they change size...

5. What star patterns have you observed?

uhMm..hMm... _______ belt...[forgot the first name]i remember seeing a belt and a warrior...a bow..i don't know their names..lol..

6. How are stars grouped in the universe?

they are grouped through constellations..?

stars form and die and become dwarfs and black wholes and they r formed out of gasses and depending on the lights form i thnk and patterns and color thats how hot it is. stars for a constellation im too lazy to type more so bye bye

Quite a bit, as i am majoring in astronomical meteorology.


2. How are stars different?

Stars are different from Planets in that they are creating energy rather than absorbing it.
Stars are different from each other in that they are different sizes, different ages, different stages of "life"
The birthpath of a star is very basic: It is born, it grows, it uses up everything it can, then it either goes one of three ways: Neutron, White dwarf, or black hole(it's believed at this point)
I will edit in a nice pic that shows this... if i can find it.. it's really a great pic.


3. How do stars form?

Stars form from nebulous gasses inside a patch of space called a Nebula, this is an area filled with Helium, hydrogen, iron, dust particles from various space debris, this all comes together via gravity. There my be very little actual gravity at the very beginning, but as molecules combine and collect, they create more and more gravity pulling things to it. until the pressure gets so tight that it compresses into fission.

*note this is a death of a star...note the gases expelling from it.




4. How do stars change?

Stars are changing all the time, but i'm sure you're asking about how they change from each stage.
To understand this, you have to understand how a star works.

Stars are burning, they are burning from fusion and fission, not from fire.
There is another pic i can think of that would adequately describe this....
The star has to balence out it's gravity with the pressure building inside it with fission. This is due to the amount of fuel being consumed all the time. The "body" of a star is always fluxuating in and out as materials are being consumed. As the baser materials are completely consumed, the star has to reach further and further in to space to find material to consume. this creates a type of negative pressure that expands the star (this stage is called supernova) when this stage happens to our sun, the first three planets are going to be consumed. This stage is very fast (in astronomical terms) and will be extremely hot. The sun will then shrink down to half, if not less, the size it is now, and be VERY VERY cool, this stage is called White dwarf.
ie the death of the sun.




5. What star patterns have you observed?

Too many to list here.


6. How are stars grouped in the universe?

So far it's believed that stars are grouped by gravitational forces that collect or repel the systems. Most galaxies are believed to have a black hole in the center of them that is slowly but surely consuming the stars in the galaxy (yes including our own) These black holes are pulling others in to each other (i will also edit in a pic of this in action.... very cool colliding galaxies)

*note the two galaxies on the lower right side... THAT is a collision drawn by gravity.
Ok.. will be back to edit in those pics...
Edit: Added pictures to illistrate my statements

^ You have a fanboy. ;)

I think there's something wrong with one of your statements. I don't think stars "create" energy, as this is fundamentally impossible (Law of Conservation of Energy) ~ and your further explanations (regarding the expansion of the star) shows that it still follows the Law of Conservation of Energy since it needs to consume material from within it's proximity.

Ooh... Betelguese. One of my favorite stars. Forms the shoulder of "orion", if I'm not mistaken.

^ What i was meaning is that they are creating energy as opposed to just SUCKING engery... Stars are giving off TONS of energy in the form of radiation, heat, etc etc etc... while what the hell does earth give off?
uhm... radio waves? maybe some Infrared light? Tiny tad of heat...
All miniscule in comparison to what's being given off by the sun for example.

We can see stars, due to the amount of energy they give off, while we CAN"T see planets (viewing with a telescope ie of Hubble magnitude)
All we can see is the gravitational effect on said star. ie the wobble effect it gives.. Which is why we believe that andromeda galaxies have planets in it.
More than likely MOST star systems (solar systems for lack of better word) have planets in then, BUT... we just can't see them yet.

*side note - Maybe we could adapt the Chandra Tele's to view the infrared from planets... hmm... it'd have to be modified to view further, than just our sun... and it's really a shame to remove a view of the sun, as we are still learning about it.... hmmm
Ok rambling thoughts over...

wow people here are encyclopedia ..hmhm

i was interested how they are related of "causing " illness, actually as i know from my parents and grandfathers and so on specific stars they know appears in specific months or seasons to indecate the weather that "may" usually have high incedence of sickness they prevent that by stop eating some sort of food like watermilon mango or drinking cold/freezing water and i believe that because it comes from experience.
