quasars.
What color is epsilon sagittari?
blue those are the brightest stars
What the difference between universe and galaxies?
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
Are the brightest comets those closest to the sun or those farthest from the sun why?
neptune is the farthest planet and mercury is closet planet

What is the specialty of Andromeda 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.
What causes the light in 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.
What galaxies that most resembles own galaxy shape?
Those are the spiral galaxies. In our "immediate neighborhood" (part of our Local Group), we have M31, a.k.a. the Andromeda Galaxy.
An observation of the red shift of galaxies suggest that the universe is?
... expanding. The redshift is attributed to the Doppler effect, meaning that those galaxies are receding, or getting away, from us.
When scientists look at very distant galaxies through powerful telescopes they see the galaxies as they were millions or billions of year ago Why is this?
The vast distances involved means that the light we see left those galaxies a long time ago.

How is light years used in science measurement?
A light year is the distance light travels in a year. That is roughly 6,000,000,000,000 miles (six trillion miles). Thus such a unit is used only to measure the largest distances, those between stars and galaxies.
