Are all parts of the sky pretty evenly spread with stars and galaxys?

Answer 1

The stars are not evenly spread out through space. Stars are concentrated in galaxies. However galaxies are evenly spread though the universe. If you were to look form outside the universe, from far far away, you would see that any direction that you would look at looks the same as any other direction.

Others are correct to say that galaxies come in groups, and super clusters. Those are just larger and larger categories. However even groups of galaxies and galactic super clusters are spread evenly though space.

Here is a deep space photograph from Hubble Space Telescope:

Each one of those dots, and little streaks of white, bluish and orangish colour is a galaxy. To me they are spread pretty evenly. Some are brighter then others, and some may be closer or further away then otheres. But they are pretty uniform.

The way that this can be explained is through the formation of the universe. They think that the gas and dust (that made up stars which make up the galaxies) in beginning (13-14 billion years ago) was spread out pretty evenly. But if you zoomed in close enough there were very little over- and under-densities from which galaxies were created. Sort of like when you look our on the lake and the water seems very smooth, if you look closely, there is the tiniest ripples.

Answer 2

No. If you look at the Milky Way you will see millions of other stars that can't be seen in other directions. This is because the galaxy we live in is a flattened disk. When you look at the Milky Way you are looking along the disk portion of our galaxy. We can see more galaxies when looking away from the disk of our galaxy because there are fewer stars and dust clouds to obscure our sight.

Answer 3

No, there's a strong bias of stars towards the Milky Way, so the
non-Milky Way-centered fall and spring skies have fewer stars.

The summer sky has the brightest Milky Way and fewer bright stars, while the winter sky has more bright stars and less bright Milky Way.

Answer 4

Nope, although it apears that way.

Space has lots of just that, space. Take a look at some of the pics of the Apollo program and check the number of stars when they are in Earth/Moon orbit. Also look at the Earth rise picture.

The Universe is a really big place, with lots of empty space.

Answer 5

No No and No. There are some parts of the sky where you can hardly see anything, and some areas, such as the area of the sky where you can see the Milky Way, where you can see thousands of stars.

Answer 6

At some higher order level, sort of.
However, stars are almost al confined to galaxies, and galaxies occur in groups, called (in heirarchical order) clusters, superclusters, sheets, and filaments.

Answer 7

No not at all, just look along the plane of the galaxy, then look upwards or downwards.

Answer 8

yes!! isn't it great??
