blue those are the brightest stars
neptune is the farthest planet and mercury is closet planet
A universe is a very big realm of darkness with galaxies in it. and there are billions of galaxies in the universe! One of those galaxies is our solar system, and in that solar system is our planet. There probably is even more then just one univserse. O_o Well... Galaxies are within the universe and a universe is defintly bigger then a galaxy
Galaxies can have a wide range of colors depending on the stars they contain and how those stars emit light. Generally, galaxies appear in colors like white, blue, red, and yellow. These colors relate to the age and types of stars present in the galaxy.
It is a large galaxy, which is relatively near-by. There are galaxies nearer to us, like the two Magellan Clouds; but those are mini-galaxies.

A galaxy is made up of hundreds of billions of stars (suns). The light from the galaxies comes mainly from those stars.However, in early galaxies, a much larger amount of energy was released from the quasar - currently believed to be the gigantic black hole in the center of galaxies.
Those are the spiral galaxies. In our "immediate neighborhood" (part of our Local Group), we have M31, a.k.a. the Andromeda Galaxy.
The vast distances involved means that the light we see left those galaxies a long time ago.

Superior planets (those outside Earth's orbit) appear brightest when they are at opposition, which is when they are on the opposite side of Earth from the Sun. This is when they are closest to Earth and fully illuminated by the Sun.
