Why are some people so ignorant,
to the idiot below and you know who you are,
my daughter has written this question and this is quite clearly my account,
She's not pretending to be a kid,
She really is one

Hi Chloe, you have the same lovely name as one of my daughters :~)
Stars are really great big balls of fire in Space.
They are mainly made from Hydrogen and Helium.
There are lots of other things in a star as well but its mainly those 2.
If you have seen a film showing a really really big explosion of a bomb, that is a little like what is happening in the sun.
They are really an explosion in space, the Hydrogen burns very hot and turns into Helium and stars are burning away in an explosion that will last for millions and millions of years.
Stars are basically very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements.
Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them.
After a star runs out of fuel, it throws a lot of its material back into space. New stars are formed from this material. So the material in stars is recycled.
Hopefully this is what you wanted to know and I hope I've help develop another budding Astronomer!
Have Fun!
:~)

Massive luminous balls of plasma. They shine because nuclear fusion in the core releases energy which then traverses the star's interior and radiates outward.
They begin as a collapsing cloud of material that is composed primarily of hydrogen as well as helium and other trace elements.
Once the core becomes dense enough some of the hydrogen is steadily converted into helium through a process called nuclear fusion. The remainder of the interior caries energy away from the core through radiation and other convective processes. These processes keep the star from collapsing onto itself and the energy created creates a stellar wind.
A star is so hot metals like Iron exist only as gas.
In essence a star is a mass of incandescent gas a gigantic nuclear furnace where hydrogen is turned into helium at a temperature of millions of degrees.

What are stars made of?
Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb. Even though it is constantly exploding in a nuclear reaction, the Sun and other stars are so large and have so much matter in them that it will take billions of years for the explosion to use all the "fuel" in the star. The huge reactions taking place in stars are constantly releasing energy (called electromagnetic radiation) into the universe, which is why we can see them and find them on radio telescopes such as the ones in the Deep Space Network (DSN). Stars, including the Sun, also send out a solar wind and burst out occasional solar flares.

All new stars are made out of Hydrogen and very small p.c. of Helium. historic stars maximum likely die out because of lack of hydrogen that's considered the inspiration for star gas; also historic celeb might want to have intense p.c. of helium and little of carbon. Stars as such might want to both blow up or end up neutron stars. If a celebrity is an massive superstar, it is going to develop right into a black hollow.

When stars form they are composed of about 70% hydrogen and 28% helium, as measured by mass, with a small fraction of heavier elements. Typically the portion of heavy elements is measured in terms of the iron content of the stellar atmosphere, as iron is a common element and its absorption lines are relatively easy to measure. Because the molecular clouds where stars form are steadily enriched by heavier elements from supernovae explosions, a measurement of the chemical composition of a star can be used to infer its age. The portion of heavier elements may also be an indicator of the likelihood that the star has a planetary system.
The star with the lowest iron content ever measured is the dwarf HE1327-2326, with only 1/200,000th the iron content of the Sun.

Basically, glowing gas.
Like a Neon Tube light. The gas in the tube glows giving us the light.
Our Sun is a star that is glowing and it gives us light.
It is made of hydrogen and helium gases.

Stars are made of atoms of hydrogen fusing together and forming helium, and other things fusing together making lots of energy and elements.
Also stars are super-dense in the middle and super hot, so much so that a piece the size of your thumb would be about as heavy as you are and at 14500000 degrees Celsius.

They're made of hydrogen. By nuclear reaction they turn the hydrogen into helium and this emits heat and light as a by-product.

Stars are made from the tiny specs of dust of the moon fairys who grant children's wishes on their birthdays.
Don't worry about the hygrogen, oxygen, gasses stuff until you are at least 30years old.
