Which stars are actually a galaxy?
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
What are all stars and galaxies in?
All stars and galaxies are in the universe.
How many galaxies and stars are there in the univese?
The number of the galaxies has never, nor likely to be, accurately counted. Certainly there are many billions. As there are many 100s of millions of stars in an average galaxy then the number of stars is uncertain, but very large.
How many stars are in galaxies millions or billions?
Billions at least, in the large galaxies. Obviously it depends on the size of the galaxy. It is estimated that in our Galaxy there are at least 100 billion and perhaps as many as 400 billion stars. Many galaxies are same sort of size as ours and some are much bigger. However, there are a lot of small "dwarf galaxies" The smaller dwarf galaxies have millions rather than billions of stars.
Do stars form into galaxies?
Galaxies are vast collections of stars. So I guess you could say that a big group of stars forms a galaxy. Our galaxy has many big clusters of stars within it, so not all star clusters are galaxies. If you have a cluster of several million or billion (or trillion) stars surrounded by a lot of empty space, that is probably a galaxy.
How many stars do the largest galaxies have?
The largest galxies have stars numbering in the tens of trillions.
How many stars are in the largest galaxies?
Anywhere between 100 and 1,000 billion stars
Are there any stars between Galaxies?
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
Do Galaxies contain millions of stars?
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Which objects began to form in your universe earlier stars or galaxies?
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
What determines the shape of a galaxy?
The shape of a galaxy is primarily determined by its rotation and gravitational forces. Spiral galaxies, for example, have well-defined arms due to the rotation of their stars and gas. Elliptical galaxies have a more rounded shape due to the random motion of their stars.
What galaxies are smaller with many bright young stars and lots of gas and dust for star formation?
Spiral Galaxies
