A huge collectio of stars, dust, and gas held together by mutual gravitational attraction
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
heroin.
Basically it is asking what the definition for galaxy is, it is: A gaint structure that contains hundreds of billions of stars.
Another word for galaxy is "star system" or "stellar system."
This is "galaxie" pronounced "galaxi"

Galaxy = la galaxia
Two galaxies that look to be the same.
The Galaxy, or Milky Way, is from the the Greek word for milk. The word galaxy is Greek and means 'milky circle' aka Milky Way.
A galaxy is a system of stars, gas, dust, and largely dark matter that are bound together by gravity. Our home galaxy fits this definition, so it is called a galaxy.
There is no evidence that our GALAXY is expanding. Are you confusing the word galaxy with the word universe - if so they are NOT the same thing.
