Are there stars in the universe that are bigger than the entire Milky Way?

That's thought to be unlikely.
The largest star known of so far is VY Canis Majoris, whose radius could be
2,100 times the sun's radius. If it were located in place of the sun, its 'surface'
would be somewhere around the orbit of Saturn.
Mashing together everything known today about stellar evolution, and what
goes on inside stars as they grow, age, and die, it's been hypothesized that
the largest possible single star is probably around 2,600 the radius of the sun.
Let's make it an even 5,000 times the size of the sun, and see where that would get us:
A star 5,000 times the size of the sun would fit inside the orbit of Neptune.
Its surface would lie about 0.00077 of the distance to the next nearest star,
and its diameter would be about 0.00000000773 the diameter of our galaxy.
So you can safely say that even if astronomers are wrong about the largest
possible size, and wrong by a factor of a hundred, or a thousand, or a million
times, that still doesn't put it anywhere near the size of the Milky Way.
They would have to be wrong by a factor of more than 3,000 times in order for
the biggest possible star to reach only from the sun to the next nearest star.

Is there in the universe stars that are bigger than the entire Milky Way?
Of course, there's more than one life form in this universe
How many solar system are there in space?
Our own galaxy has between 100 and 400 billion stars; there are hundreds of billions of similar galaxies in the OBSERVABLE Universe, and it is believed that the entire Universe is much, much bigger than the observable Universe (how much bigger, is not known). It seems that at least a large percentage of those stars have planets, which means they can be called "solar systems".
Is it true the universe is not bigger than the world?
No. Of course not. The universe is big enough to hold earth and all the other planets in the Milky Way Galaxy and all other galaxies and the sun and the moon and the stars. There is no way that the universe could be smaller that Earth. =)
Which are the oldest stars in the Milky Way population 1 or 2 stars?
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
How many of the eight planets are in the milky way?
The entire solar system is in the milky way, with all the stars you can see.
Is the milky way a universe?
No. The Milky Way galaxy is just one of billions of galaxies in the Universe. Just like there are billions of planets in the Milky Way Galaxy, there are also comparable numbers of planets in other galaxies.
Are there more galaxies in the universe than stars in the milky way?
According to what Carl Sagan that is true
Milky Way galaxy bigger than the sun?
The Sun is one of approx. 200 billion stars in the Milky Way galaxy.
The universe is made of only your solar system?
No. Our own galaxy contains several hundred billion stars (each of which might be a solar system), the observable Universe contains hundreds of billions of galaxies, and it seems that the entire Universe is much, much bigger than the observable Universe.
Are there stars in the universe that are bigger than your entire galaxy?
None that we know of. The Milky Way is a bit larger than the average galaxy, with somewhere between 500 billion to a trillion stars (it's difficult to know, because there are an unknown number of small and invisibly dim red or brown dwarf stars). We don't believe it possible that any single star to be much larger than about 150 solar masses.
Is there any other galaxy with stars and planets other than the milky way?
Yes, actually there are trillions of other galaxies with stars, and planets in the universe.
Is the milky way a group of stars?
Yes. A group of stars called a galaxy. One of billions in the Universe. An awesome thing it is too. Truly awesome.
