The same as on Earth - but in different proportions. Most stars are made up almost entirely of hydrogen and helium; the so-called "metals" (heavier elements) are present in much smaller quantities.

∙ 13y agoThe stars in globular clusters are among the older stars; they were formed in great part from the "original material" of the Universe, and thus have a lower "metal" content. Thus, they consist mainly of hydrogen and helium. The "metals" (heavier elements) were created mainly in supernova explosions, and then enriched the material for newer stars (such as our Sun), which has a greater proportion of "metals".

∙ 15y agoYou require three elements to create new stars:
1. Hydrogen
2. Gravity
3. Time - LOTS of time.
Given those three things, stars will form.

What are the main elements that make up a star?
For main sequence stars, the vast majority is hydrogen and helium. Older stars will exhaust these lighter elements near their cores and begin fusing heavier elements.
Why do younger stars have more elements?
Shortly after the big bang, the first stars were formed - Population III stars. These comprised of nothing more than hydrogen and helium and maybe a little lithium for good measure. When these stars died, they would have exploded as massive supernova and spread the first 26 elements into the Universe. These 26 elements would have mixed with hydrogen and helium to make the next set of stars - population II stars. Most of these stars, when they died, would have exploded as supernova, enriching the Universe with the rest of the elements. These elements, along with even more hydrogen and helium, combined to make our Sun. Our Sun is a metal rich star or population I star. Just in case your wondering what the next set of stars will be called, I have no idea - Population 0 maybe?
What continues to give the sun its heat andenergy and light?
Its very own fuel: made up of hydrogen, carbon, and a few other elements. Stars were given 4 basic elements hydrogen carbon something something look it up. They used these to make new elements: all the elements on the periodic table. You are made up of elements created by stars long ago.
Subsystem of the universe?
The first subsystem would be the super cluster, or clusters of galactic groups. After that would be groups, such as our local group of galaxies. The galaxies would be the next level. Within a galaxy are numerous globular clusters of stars, and random stars (and binary and ternary pairs) orbiting the disk (for spiral galaxies). There are various types of galaxy. Each star may be orbited by zero or more planets, belts of asteroids, and/or comets, forming a solar system. Each planet may have a ring of debris and/or moons. Some of these moons may have satellites of their own, though I am not aware of any such in our solar system.
What elements are formed by stars less massive than your sun?
It depends exactly what you mean. You probably mean the Red Dwarf stars. I only know of one element that they make and that's Helium.
How many stars make up a globular cluster?
a billions of stars
What is a name for many stars?
Many stars together can make up a galaxy. Depending on the arrangement of the stars, they could either make up an elliptical, spiral, barred spiral, lenticular, or irregular galaxy. Stars can also be together by gravity in clusters. Stars that are clustered together in a spherical group are called globular clusters. Many stars are binary stars, meaning that 2 stars circle around either each other, or around a central point of gravity. These are the most basic star groupings in which there are "many" stars.
What did these first generation stars make?
First stars made the smallest elements, from hydrogen up and progressively larger stars made progressively larger elements
What are the main elements that make up a star?

What are elements called that make up a star?
Stars are composed mostly of hydrogen and helium.

What is the relationship between the periodic table and a supernova?
The elements on the periodic table were created by stars through nuclear fusion. We use the term stellar nucleosynthesis to describe what stars are doing through fusion. Stars fuse hydrogen into helium, and then start making heavier elements by a different fusion process. But stars can only make elements up through iron. They can't make the heavier elements. Enter the supernova. A supernova is that "big blast" that occurs at the end of the life of some stars. In a supernova, the trans-iron elements are formed. That is, all the elements heavier than iron are formed in a supernova. Because the elements heavier than iron are formed in a supernova, we can say that there is a relationship between the supernova and the periodic table of elements.
What are the most abundant elements?
The first is hydrogen, and the second is helium, they make up 97% if the mass if the stars.
What do you call a group of baby stars?
That would probably be a globular cluster. (A galaxy usually has more stars than that - from several million to several billion stars.)
Why are stars distant from one another?
Actually the typical distances between stars vary a lot. Inside a globular cluster, you can have a million stars or so, which are much closer together than in our region.If you ask "Why are they distant from one another in our region of the galaxy", I would say that that can POSSIBLY be answered by the anthropic principle: if stars are much closer together, the conditions MIGHT be catastrophic, and make it difficult for life to survive.
Why are star clusters ideal 'laboratories' for stellar evolution?
Star clusters are ideal for figuring out certain things of stellar evolution because every star in a cluster is made of basically the same material and therefore has the same composition, they are basically at the same distance from the earth, and they all basically move the same way. This is ideal because it can be tough to determine whether some stars are closer or farther away (brightness would make you think that a brighter star is closer but this is not always the case) but looking at 2 stars in the same cluster, if one looks brighter, it actually is! These clusters make it easy for astronomers to see how stars grow up!
