Our Milky Way is about 100,000 light years across. Some galaxies are larger than that, some are smaller.

What a space contains?
whatever you put in that space. If you are talking about the space (Outer Space) then there are planets and moons and stars and stuff, too much for your puny brain to understand
How many solar system are there in space?
Our own galaxy has between 100 and 400 billion stars; there are hundreds of billions of similar galaxies in the OBSERVABLE Universe, and it is believed that the entire Universe is much, much bigger than the observable Universe (how much bigger, is not known). It seems that at least a large percentage of those stars have planets, which means they can be called "solar systems".
How universe is changing?
The universe is expanding, and it was recently discovered that the universe is expanding much faster than was originally thought. Also, objects within the universe are constantly changing, such as the birth and death of stars, expanding and/or contraction of gas clouds, and objects in motion (the spinning of galaxies and solar systems, rogue stars or planets) are constantly changing.
What are things in space?
EVERYTHING galaxies, nebulae, stars, planets, milky way, star clusters, globular clusters and much more
What does modern astronomy study?
Yes, astronomers study stars, planets, and other heavenly bodies. The word has its origin in the Greek "astron" which means star, although the science includes pretty much anything outside Earth's atmosphere.

How is the formation of stars different from the formation of planets?
Planets are pieces of material that orbit a star such as the earth orbits the sun. Stars are 'suns' and are distributed throughout the universe. Stars are much larger than planets hence the reason that at night stars can be seen in the sky and planets cant even though the stars are much futher away than the other planets in our solar system.
What are the advantages of space travel over using telescopes to explore the universe?
It will get the planets to be much larger and it will have a percale view of some uranium planets
Where does asteroid come from?
Asteroids are small fractions of much larger stars, planets, and rocks in space.

When compared with most stars are planets brighter or smaller?
Well,planets do not have any light of their own so they are definitely not brighter and yes there may be some stars smaller than the planets but most of the stars are bigger than the planets . But on the whole the Space is not that much explored so that we can get any cumulative answer.
What are some ways that stars and planets are similar?
Planets and stars are similar:FEW OF THE WAYS ARE :Both the stars and planets moveThey are celestial objectsThey are studied by astronomers
What so stars do in outer space?
Stars would appear much like our Sun when viewed at closer range and most would have planets and other objects orbiting them.

How many stars existed on the beginning of the Universe?
If the big-bang theory is true, the stars, planets, and other universal bodies were progressively formed, so there were much less stars than we have today, and the fomation of new stars is compensated by the death of others.
