Astronomers say there are more than one galaxies in the universe?

Question

Is that theory or fact? Fascinating stuff.

Answer 1

First, let's make sure we agree on our terms. A solar system is a star and the planets, comets, asteroids and other bodies orbiting around it. A galaxy is a very large cluster of stars (solar systems) all orbiting around a common center. Galaxies are very far apart from each other in most cases. Nearly every star we see in the night sky is in our own galaxy, including the ones that don't appear to be in the "milky way". We can only see a very few other galaxies without a good telescope. The most visible galaxy outside ours is the Andromeda galaxy in the constellation Andromeda. (Actually, it is way beyond any of the stars in that constellation, but that's the direction to look.) It looks like a faint, fuzzy star.

But there are billions, probably trillions of galaxies, most of which no one has ever seen. We know this because the Hubble Space Telescope has taken long exposures of tiny blank spaces between stars and revealed thousands of galaxies too faint to be seen any other way. The most detailed photo is called the Hubble Ultra Deep Field. Check out the links. Watch the video on the first one. The last one is the full-size image itself.

Answer 2

There are billions of galaxies in the universe. This is a fact. Look up the Curtis/Shapley debates of the early 20th century, and 'standard candles' that were used to make the distinction - Cephied variable stars and type Ia supernovae.

Answer 3

Fact. Millions upon millions of galaxies have been detected, stretching out towards the farthest reaches of the Universe. It is estimated that there are at least a trillion galaxies in the Universe.

If you thought 'Wow, the Universe must be a big place!'...well, you're right. ;P

Answer 4

Billions of galaxies! Fact!

Answer 5

There are many, many, many galaxies in the universe. Our galaxy is the Milky Way, and it's just an average galaxy in an average universal neighborhood.

Answer 6

there are more than one galaxy in the universe because our galaxy, the Milky Way, is a bar spiral universe or a spiral universe (depending upon which scientist you listen to). They also have proof of irregular galaxies and there was another kind, but i forgot what it was called. however, it is fact.

Answer 7

theres over 100 billion galaxies in the universe; thats
100,000,000,000.

Answer 8

There are alot of galaxys in the universe.
Milky Way, Andromeda, Triangulum, M32, M49, M59.

Answer 9

in fact there are Billions of galaxies and that's a fact because we can observe them with telescopes.

Answer 10

there r like infinity numbers of Galaxy's....the stars u c at night is out Galaxy....u cant c other Galaxy unless u use a telescopes
