Milky Way Galaxy

Milky Way: About 100,000 light-years in diameter

Universe: Unknown, but the observable Universe has a diameter of about 92 billion light-years.

Solar System: There are different definitions for the limits of the Solar System; if you include the Oort Cloud, you would have a diameter of about 4 light-years.

That's a radius of about 2 light years, taking you about half way to the nearest star.

With many other commonly used definitions, the "Solar System" is much smaller.

Every star you see is in the Milky Way, so you can say it is visible throughout the year. A particular line that looks like a trail or a sort of milky way goes through the night sky and can also be seen all year round in different constellations.

Maybe someone who is trying to prove that and doesn't know the right answer

The 'stars' are any celestial object that reflects the light from the sun... This can be something as small as a man-made satellite - or as large as a whole galaxy !

Galileo Galilei

they beilive the milky way was formed in an indonesian and it is very complexist in this tixtures and especially cos they used a camera and stuff in there alwys in evrything

I dont like art, i LOVE art. I love painting and Drawing. I love it so much because its good to use your imagination to paint/draw things, and then when its finished its a masterpeice

yes, the milky way it is a barred spiral galaxy

Depends what you mean by "significance."

We know there is SOMETHING out there in our Universe that exerts a gravitational force but does not otherwise interact with ordinary, baryonic matter. However, we do not yet know what this stuff IS. So, in the same way that highly penetrating rays are still called 'X' rays -- even though they are no longer so mysterious that we need to give them the moniker 'X' -- we presently call this stuff "dark matter."

When we finally are able to figure out what dark matter is, it will most likely radically change our understanding of the nature of our Universe -- in the same way that x-rays did.

It may turn out that dark matter will have no effect on our daily life. Or, once we understand what this stuff is, it may turn out to be as important to us as x-rays are today. In that sense dark matter may or may not have much "significance" to most people.

There are lots of spiral galaxies, so you shouldn't speak about the spiral galaxy as if there were only one, and while there are lots of moons inside galaxies, you may be thinking of galaxies that have other galaxies which orbit them; our own galaxy, the Milky Way, has the Greater and Lesser Magellanic Clouds as satellite galaxies, which perhaps is what you had in mind. A satellite galaxy is not a moon, however.

Over 100 billion just in ourgalaxy. So more than 100 billion stars in a galaxy!

The Sun's light actually reflects from the moon and reaches the Earth. That's why it's really bright, compared to a normal night, on full moons.

We are in the Milky Way Galaxy, therefore we see at clear nights interstellar dust illuminated by starlight. The dust is in a form of a spiral arm which we see only part of as a narrow band.

They are in space. (: you're welcome.

It is a radiotelescope which works on radio waves instead of light waves.

The local group is a collection of galaxies. It is not a galaxy on it's own.

a few billion

The thiele tube allows convection currents in the oil when it is heated meaning there is fairly uniform distribution of temperature.

Lemon juice or even milk can be used as ink. When heated by an iron or light bulb, the ink will turn brown. It doesn't necessarily disappear when cooled off again. There are other chemical inks that will fade out with the cooling off, but I don't know their availability to the commercial market.

Hit, walk, hit by pitch, fielding error, catcher interferrence.

1. Walk 2. Hit 3. Hit by pitch 4. Strike out and catcher misses the ball allowing batter to reach 1st base. 5. Reached on Error 6. Fielder's choice 7. Interference by catcher or other fielder

The largest star in Orion is Betelgeuse with a solar radii of 1,180.

D. The sun.

All planets in our solar system orbit the sun thus it is the best reference when describing the motion of the planets within that solar system.

You can get an EMI detection device that will be able to locate exactly where EMI is being given off such as TV's Computers, Microwaves. A much easier way would be to look around for any medium or larged sized eletronic devices, they are most likely giving off EMI.

as far as I know there is no farthest galaxy from earth. However There is (Of course) a farthest Visible galaxy. However I do not know the name of this galaxy. (I hope someone comes along and improves my answer to this question.)

Neclear Fusion because stars are powered by that, even our sun
