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.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
There are billions of galaxies. Most stars are born in one galaxy but others are pulled in by the huge gravitational forces of the black hole in the centre.
If it didn't have stars it wouldn't be a galaxy
The answer is Galaxy. a circular collection of stars is a galaxy
There are about 200 -> 400 billion stars in our Galaxy
All stars we currently know of are part of a galaxy. Stars are born within galaxies from clouds of gas and dust. If a star were to exist without belonging to a galaxy, it would likely be a result of very rare and extreme circumstances, such as being ejected from its parent galaxy due to a collision or interaction with another galaxy.
The Milky Way galaxy has spiral arms where a lot of new stars are being born, including the Orion Arm where our solar system is located. These spiral arms are regions of higher density that promote the formation of new stars due to gravitational interactions between gas and dust.
the milky way is everybodys galaxy and yes the stars you see are in your galaxy
Yes, stars can exist outside of a galaxy. These stars are typically referred to as intergalactic stars, and they may have been ejected from their original galaxy due to interactions with other stars or galactic dynamics. Intergalactic stars are typically found in the space between galaxies.
The number of stars in a galaxy remains relatively stable over time, as stars are created and destroyed continuously through processes like supernovae and star formation. However, galaxies can merge with one another, which can increase the total number of stars in the resulting combined galaxy.
