Because they're hundreds of thousands of light years away from Earth.
Yes. Far-away galaxies can be mistaken for stars and occasionally are. This is due to the galaxies being millions upon millions of light years (the distance light can travel in a year) away from earth.
A faint galaxy appears as not shining, and look faint from the earth due to distance.
use a teloscope, or look overhead at the milky way. You are part of the galaxy use a teloscope, or look overhead at the milky way. You are part of the galaxy
If the Universe was shrinking the galaxies would appear to be moving towards the Earth, and look more blue than they should. This is the opposite to the universe expanding where galaxies would appear to be moving away from the Earth, which we know due to "red shift". Andromeda would be the exception since it's directly moving towards the Milky Way.
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
Earth doesn't have rings. Look up the pictures of Earth from space. Jupiter does have rings but they're extremely faint. They're made of dust while Saturn's rings are made of rock and ice. The rings are so faint they weren't known until 1979, when the Voyager I probe flew past Jupiter.
No.
they see the past when they look up and see the galaxies. its looking back in time because light can take years to travel to earth and so its like their looking at the youth of the galaxy.
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
Galaxies change very slowly.
People see energy differently. It can look like colour, like heat waves, like faint smoke, and even like gas.
