We only name things that we can see, or detect. The first stars in the universe were likely supergiant stars that exploded in supernova explosions within a few hundred million years.
The material blasted into space by the first three or four generations of rapidly-dying stars provided the raw material that came together to form our solar system.
The prevailing scientific theory is that the universe started with the Big Bang.
Population II stars are the oldest in our Milky Way. Population III stars were the first stars in the Universe, but have yet to be discovered. See related question
We haven't observed all of the stars in the Universe, so we don't know what is the largest yet.
It is very easy to answer- First, I want to tell that , what is a universe? A universe is a limitless space with billion of stars in it. So,lets come to the point.There is no boundary in the universe as it is a very vast space and billion of other universe are also there. I wish that you could understand it
Most of the light in the universe comes from the stars. Stars create their own light using nuclear fusion.
The prevailing scientific theory is that the universe started with the Big Bang.
The first neutron stars likely formed some time in the first 600 million years after the Big Bang when large stars of the first or second generation died.
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
The Universe.
The remnants of the big bang initially. Then the first stars formed.
A galaxy contains billions of stars. A universe contains billions of galaxies.
