Yes because stars are dying and being born constantly.

Are there other planets Andromeda galaxy?
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
What does the size of a galaxy mean?
The size of a galaxy means how old the galaxy really is and also the stars indicate how old the galaxy is. So both the size nd the amount of stars indicate how old the galaxy is.
How many stars are there?
There are an estimated 100 to 200 billion galaxies.Scientists estimate that our Galaxy (The Milky Way) contains 200 to 400 billion stars.So taking a conservative number of 100 billion stars per galaxy, gives an approximate total of 10,000,000,000,000,000,000,000 stars. (which is 10 sextillion)It is unknown. The Milky Way galaxy contains an estimated 200 billion stars and there are an estimated 100 billion galaxies in the observable universe. However, our galaxy is significantly larger than most. That said, if we assume the average galaxy has 10 billion stars then we arrive at an estimate of 1,000 billion billion stars, or about 1 sextillion stars.
Is it true that in the Andromeda theres more than 800 billion stars?
Probably. The number of stars in the Andromeda galaxy is estimated to be around 1 trillion.
What is a star system?
A large number of stars with a perceptible structure such as a galaxy would be called a star system.
What is the average number of stars in a dwarf galaxy since it contains several billion stars?
The average number of stars in a dwarf galaxy is several billion.
Is 100 billion the average number of stars in a normal galaxy?
Yes. 100 billion is the average number of stars in a normal galaxy.
What are two mechanics that cause the number of stars in a galaxy to increase?
One way to increase the number of stars in a galaxy is for the two galaxies to collide.
What are two mechanisms that cause the number of stars in the galaxy to increase?
One way to increase the number of stars in a galaxy is for the two galaxies to collide.
Do all stars belong to a galaxy or can a star exist without belonging to a galaxy?
They can be outside a galaxy. For a start, stars formed within a galaxy can be catapulted out of a galaxy (when they come close to another star, and change their velocity as a result).
Are stars always in the same galaxy?
Generally stars are in the one galaxy. However, it is possible for galaxies to collide or merge, so in those instances it can change.
Why are stars in your galaxy?
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
Do galaxies typically contain between one million and ten million stars?
A dwarf galaxy might contain this number of stars. A galaxy will contain billions of stars.
What is the average number of stars in a dwarf galaxy since it contains a few million to several billion stars?
The average number of stars in a dwarf galaxy since it contains a few million to several billion stars with as few as ten million (107) stars.
At what galaxy are stars?
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
What is the average number of stars in a giant galaxy since it contains trillions of stars?
The average number of stars in a giant galaxy since it contains trillions of stars is 10 trillion.
Stars born in a galaxy?
You will need to expand on that question. If you mean how many stars are born in a galaxy then it would be inaccurate for me to give an answer because a galaxy is a vast, heavy grouping of stars, supported by gravity. There is no minimum or maximum amount of stars allowed and so a galaxy could vary quite vastly in the number of stars it contains.
