Probably, but at present we have no way to get out there. It may take tens of thousands of years to be able to get a camera out there, and then it would take another 10,000 years for the signal to get back to Earth.
Where is the Milky Way in the solar system?
There are many asteroid formations in the Milky Way. Of those, three orbit our sun, Sol. The first, and most commonly known, asteroid formation in our system is the Asteroid Belt (sometimes called the Main Belt). It is located approximately 3 AU (448,793,612.1 kilometres) from the sun, and is comprised of mostly rocky asteroids in a belt formation. The second is the Kuiper Belt, a belt formation of icy asteroids and dwarf planets. The third is the Oort Cloud, a theorized cloud of asteroids orbiting far beyond the Kuiper Belt.
Are all stars in the Milky Way galaxy the same age?
We don't know exactly, but scientists believe that red dwarf stars, which are very small and very slow-burning, may date from the early history of the universe about 15 billion years ago. The problem is that red dwarf stars are very small, and so very dim; and thus difficult to see from any real distance.

Why does the sun circle the Milky Way?
it is so we get hours,days,weeks,months,years and leap years
Well, no. That is what happens when the planet earth orbits the sun.
Our sun doesn't exactly orbit the Milky Way. Rather, it travels along with it along one edge.
What bodies are in the Milky Way?
There are four major arms in the Milky Way
* 3 kpc and Perseus Arm * Norma and Cygnus Arm with a new extension. * Scutum Crux Arm * Carina and Sagittarius Arm There are also a number of smaller arm, or spurs.
* Orion Arm (Of which the Milky Way (Our Galaxy) is included) * New Outer Arm

How many Earths can fit in the Milky Way?
There are eight planets in our Solar System.
As of May 2010, 455 planets have been found outside of our Solar System.
There are an estimated 200 -> 400 billion stars in the Milky Way Galaxy.
So there are likely to be billions of planets in the Milky Way Galaxy.
There are 8 Mercury Venus Earth Mars Jupitar Saturn Uranus Neptune (Pluto is a dwarf)
The Milky Way was born when countless warm gas clouds come together under the pull of gravity. When the cloud collided, Stars were born. Nine billion years after its birth, the Milky Way settled down. there is a huge black at its centre, it is quite. The Galaxy now consists of billions of stars arranged in a beautiful spiral shape.
Can the Andromeda galaxy have more gravity than the milky way?
They are both spiral galaxies, except the Milky Way is a barred spiral and the Andromeda is a typical spiral galaxy. The Andromeda has at least twice as many stars as the Milky Way, and it has more mass. The galaxies are going to merge in 4 billion years, and now they are about 2 million light years apart.
What is the weather like on the milky way?
Like a long (milky colored) cloud in the sky - that moves with the stars and not the wind.
How big is the Milky Way in parsecs?
According to newest observations, 258,000ly across, or 1.5167 quintillion miles. but 18 zeros are quintillion in the USA, remember that in some places like mine 18 zeros is a trillion.
Who invented the milky way bar?
Because people thought the milky way needed something to represent it's creaminess.
Where is the milky way compared to earth?
Interestingly, it doesn't matter whether you prefer the answer in kilometers,
in miles, or in inches. The exact figure is still zero. Earth is IN the Milky Way.
It wasn't until telescopes that people realized that the band of light reaching across the sky, called the Milky Way since ancient times, was actually made of an immense number of stars. Astronomers still did not really understand what they were seeing until the 20th century, however.
Until the 1920s, astronomers thought that what we now know to be our Milky Way Galaxy to be the entire universe, and that our whole universe was a few thousand light years across. Other "spiral nebulae" had been observed, but they were thought to be new star systems forming nearby. After Hubble (the astronomer, not the telescope named for him) observed Cepheid variable stars in the Great Nebula in Andromeda, he realized that the Andromeda "Nebula" was immensley distant, and ennormous in size, and, by extension, the other "spiral nebulae" were also huge and incomprehensibly distant. He called them "island universes", and realized that we were also in one, and that the 'Milky Way' band of stars across the sky was our galaxy's disk, seen from inside. So, even though people have been calling the band of light across the sky the Milky Way for thousands of years, it wasn't until the 1920's that we understood what it was--our galaxy!
We can see only a small part of our galaxy in visible light. Since the 1960s, radio astronomers have mapped out the structure of the entire galaxy, and shown it to be a large spiral galaxy of about 100 billion stars; we are in one of the spiral arms about 8 kiloparsecs (25,000 light years) from the center of our galaxy, more or less halfway from the center to the edge.
I think Gallileo came across the milky way in the 1600's. The cloudy band we now call the Milky Way has been known since ancient times (it's referenced in various cultural mythologies, for example). However, it was only in the past few centuries that it was properly identified as a galaxy, specifically our own.
== == The Milky Way's true age hasn't been discovered. The only knowledge we have is of a meteorite which dates 4.7 billion years ago. And yes, Galileo discovered the odd colors of the Milky Way in the 1600's. If we could escape our galaxy, scientists believe it would look like M-31(The Great Galaxy of Andromeda)
I would hesitate to talk about a "discovery" of something that is in plain sight - that people have been seeing for ... well, for as long as there have been people. Like the Sun, or the Moon, or trees, or animals - or the Milky Way.
Where is our sun located at in the milky way?
We - as in the Solar System, are located about 25,000 light years from the centre of the Milky Way Galaxy and about 25,000 light years from the edge.
The Sun and the rest of the Solar System are close to the inner rim of the galaxy's Orion Arm, in the Local Fluff inside the Local Bubble, and in the Gould Belt.

a light year is how long it take for the light to reach its place example: 1,000 light years is how long it takes for the light to reach its place answer 1,000 years
What type of a galaxy is the milky way galaxy?
The milky way is classified as a galaxy...
A barred spiral galaxy.
Yes, I believe I have seen it before on a trip to keywest. It's tough to pinpoint my exact location at the time, but we were driving close to midnight and stopped on the 7-mile bridge to look at the ocean at night. To our surprise, it was an amazingly clear night and when we looked up into the heavens the Milky Way was brilliantly shining across the southern sky.
What is the coldest place in the milky way?
The coldest place in the Universe is in the Boomerang Nebula, a cloud of dust and gases 5,000 light years from Earth. It has a temperature of -457. F (-272 C) and is formed by the rapid expansion of gas and dust flowing away form its central aging star.
Are the asteroids in the Milky Way?
Now, let's get serious. There are no aliens known to exist, just a bunch of anecdotes, and no matter how high you stack anecdotes, they never become evidence. We hope there is other life out there, and we consider it likely. But someone has to be the first form of intelligent life in the universe, and there is no evidence that it isn't us.
How many constellations are in the milky way?
This is impossible to know, although some may know how to make an educated guess. We don't know the precise number of stars in the Milky Way galaxy, and we are just now learning how to locate planets orbiting relatively close stars. So far, the planets we have discovered are very large and Jupiter-like. This is not because that is the only kind of planet there is outside of our own system; it's because the very large and relatively near-by planets are the only ones we can currently detect. It may be thousands of years before we have a decent idea how many moons there are in our galaxy. We may never know.
How is the Milky Way held together?
Gravity. All the stars orbit around a super massive black hole in the center of the galaxy. The black hole and all the other stars in the galaxy are gravitationally bound, but not necessarily locked, and travel through the universe together.
Is the milky way big or small?
Depends on what you define as "big" or "small"... The nearest star from our Solar System, Toliman (Alpha Centauri), is 4 light-years away. This is already an incredible distance, by our standards; each light-year has almost 10 million million kilometers. It would take our current spacecraft thousands of years to reach there.
The diameter of our galaxy (the Milky Way), however, is about 100,000 light-years - about 1,000,000,000,000,000,000 km., 10 to the power 18.
