Unknown ... at the present time.
It is big enough so that there probably is something out there - but!
there are no other milky way galaxys there is only one so your answer is no
We live IN the milky way galaxy...There isn't a such thing as living ON the milky way galaxy....
Well no one know for sure. Right now we are pretty sure that there isn't any in the Milky Way right now but we don't know if there are other galexies out there. And if there are then if there are living things out there.
Milky Way GalaxyGalaxy
The milky way is not a constellation
The Milky Way includes many things including space objects and much more.
There could be billions of other galaxies similar to the milky way.
The milky way is a GALAXY where the earth and the other 10/11 planets are in.
The milky way has dust, rocks,and other solar systems
The milky way "composes" an infinitesimally small part of the universe. Should this question actually mean "What is the milky way composed of?", here is an answer: The Milky Way is a galaxy and is therefore composed of many different celestial objects, including: stars, planets, comets, asteroids, cosmic dust and dark energy (hypothetically), among other things.
Yes. There have been hundreds of planets discovered in other stars in the Milky Way. It has been estimated that the Milky Way likely contains hundreds of billions of planets.
The solar system (the planets, the earth and the sun) is a part of the milky way, and rotates with the other stars the milky way consists of. The milky way is therefore not going to collide with the earth.
