because they have not developed that kind technology yet and have not finished the research they are doing now .
There are about 200 -> 400 billion stars in our Galaxy
trillions of other stars in the milkyway
Yes, astronomers have discovered hundreds if not thousands of other galaxies.
yes
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.
No space probe has ever traveled as far as the next nearest star outside of our solar system, and there are 200 to 400 billion stars in this galaxy.
Stars are suns, We are in the Milkey Way Galaxy, We have only one Star. There are BILLIONS and BILLIONS of Stars in space.
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.
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.
No. The sun is a star like any other; it holds no special place in the galaxy. The stars, including the sun, orbit the center of the galaxy. There are also stars in other galaxies.
The other "solar bodies" are called stars.
