I don't understand that. And also, why are some galaxies moving forwards while other are going away from us here?
Umm thanks.

Colour is dependent upon the wavelength of light which in turn depends upon the substance and phenomena which led to its release.
The different masses of planets cause them to have different atmospheres which then reflect light from stars differently and hence the difference in colours.
All galaxies are moving away from us, as we are moving away from everyone else.

According to theory, the Big Bang only created the initial matter from which all else was formed. Galaxies, stars, and planets came after that...and all formed under a variety of conditions relating to gravitational and other influences...thus we have a variety of types of galaxies, stars, and planets. That's the short explanation,...the long explanation is covered in several chapters of most first-year astronomy text books. It's gets rather complicated.

The elements in our solar system are affected differently by the same forces. Heavier elements are affected less by solar wind, and so our inner planets tend to be rocky bodies. Most the lighter elements - hydrogen, helium, methane, etc - were blown out of the inner solar system by the sun when it began burning - and we see Jupiter, Saturn, uranus, and Neptune with the majority of those elements.
Most galaxies are moving away from our location, but we're part of a "local group" - held together by gravity. The gravitational force is pulling several galaxies together, but really, the "local group" is a single structure, flying away from other similar structures like bomb fragments from an explosion.

It has to do with the relitivity of their movement. Two cars could be crusing at the same speed on the highway but apper not to be moving in relation to each other. Also the planets get their color from the elements that they are primarly comprised of, mars gets it red from Iron Oxide ect.

All of the elements weren't created from the big bang. They were created in the newly formed stars and nuclear reactions. The only product of the big bang initially was hydrogen and helium. Everything else was eventually made later on.

The same way people have all different colors even though they all come from one planet. Just because there is only once source does not mean there can be only one result.

Different planets have different colors because they have different compositions, environments, and atmospheres.
Earth is green and blue and brown because it has oceans and green plants.
Venus is white because it's totally covered by clouds.
The moon is grey because it has no clouds and no water and is nothing but rock.
Mars is red because its surface rocks are very rich in iron oxide, which is red.
Etc.
