You are in the milky-way galaxy, but if you mean how can you see it look straight up and to the east. It will run straight over your head.

The Milky Way is the galaxy which is the home of our Solar System together with at least 200 billion other stars (more recent estimates have given numbers around 400 billion) and their planets, and thousands of clusters and nebulae, including at least almost all objects of Messier's catalog which are not galaxies on their own (one might consider two globular clusters as possible exceptions, as probably they are just being, or have recently been, incorporated or imported into our Galaxy from dwarf galaxies which are currently in close encounters with the Milky Way: M54 from SagDEG, and possibly M79 from the Canis Major Dwarf).
As a galaxy, the Milky Way is actually a giant, as its mass is probably between 750 billion and one trillion solar masses, and its diameter is about 100,000 light years. Radio astronomial investigations of the distribution of hydrogen clouds have revealed that the Milky Way is a spiral galaxy of Hubble type Sb or Sc. Therefore, our galaxy has both a pronounced disk component exhibiting a spiral structure, and a prominent nuclear reagion which is part of a notable bulge/halo component. Decade-long observations have brought up more and more evidence that the Milky Way may also have a bar structure (so that it would be type SB), so that it may look like M61 or M83, and is perhaps best classified as SABbc. Recent investigations have brought up support for the assumption that the Milky Way may even have a pronounced central bar like barred spiral galaxies M58, M91, M95, or M109, and thus be of Hubble type SBb or SBc.

The Milky Way Galaxy belongs to the Local Group, a smaller group of 3 large and over 30 small galaxies, and is the second largest (after the Andromeda Galaxy M31) but perhaps the most massive member of this group. M31, at about 2.9 million light years, is the nearest large galaxy, but a number of faint galaxies are much closer: Many of the dwarf Local Group members are satellites or companions of the Milky Way. The two closest neighbors, both already mentioned, have only recently been discovered: The nearest of all, discovered in 2003, is an already almost disrupted dwarf galaxy, the Canis Major Dwarf, the nucleus of which is about 25,000 light-years away from us and about 45,000 light-years from the Galactic Center. Second comes SagDEG at about 88,000 light years from us and some 50,000 light years from the Galactic Center. These two dwarfs are currently in close encounters with our Galaxy and in sections of their orbits situated well within the volume ocupied by our Milky Way. They are followed in distance by the more conspicuous Large and Small Magellanic Cloud, at 179,000 and 210,000 light years, respectively.

The Milky Way is a spiral galaxy with a large concentration of stars in its nucleus. The center (or nucleus) of the Milky Way is thick, like other spiral galaxies, where the spiral arms sprout. Our solar system is located on one of these spiral arms at about 25,000 lightyears from the center. To put this in perspective it is located at about two-thirds of the way from the center to the edge of the galaxy.

The spiral arms of the Milky Way rotate around its center. It takes almost 250 million years for our solar system to make one complete rotation. When we look at the galaxy from the southern hemisphere we see the middle of the Milky Way and when we look from the northern hemisphere we see the edge of the galaxy. We can look toward the center of the galaxy but it is mostly hidden by interstellar dust particles.

There are indications that there is a blackhole in the center of the Milky Way. It is also possible that in the large, seemingly empty space around the galaxy, an enormous quantity of invisible, dark matter could be found.

You're in it!

But the arm of the milky way which is visible from Earth can be seen this time of year in the Norther Hemisphere slightly East of straight up around 9 or 10pm. The later you see it the more west of straight up it will be.

The constellation Cygnus (it looks like a giant cross) is in the northern middle part of it.

If it's actually dark enough to see it, the mily way will appear as a white swath across the sky, extending from the north to south.

Here is a photo of it which I think looks as close to real as you can get with a camera

Cameras can see more than the eye and can be manipulated to yeild brother images than the eye can actually see so it won't be as pronounced as it is in most photos.

shelf above the reeses but below the hersheys, near the middle.
Unless you're looking for King size, then you'll find those on isle 5, left side, near the end.

good luck.

'course if you're talking about the galaxy, you're in it. bub.
Now, when I was little, my father pointed to this belt of stars in the sky that reached from on end to the other. The stars seemed more clustered along that belt. He said that that was the edge of the Milky Way glaxy.

where is the milkyway?
To which reference frame does the “milkyway” belong?
==============================
Approximately 350 years ago H. Huygens introduced into a science the concept of the Ether. Since then there have been constructed many models. All of them are covered by dust on shelves of science history. But, till now, a theory of the vacuum has not been constructed. Is there a necessity to build new models of the vacuum? No! A theory of the vacuum has already existed for a long time. It was included into various sections of physics under the name of "abstract model". Let's consider these "abstract models" and we shall understand their reality.
All sections of Physics are connected by the vacuum. The first theory which describes the vacuum is the theory of an ideal gas. This theory considers The condition of particles at T=0K. The particles do not interact with one another. From this it follows, that the particles in the vacuum should be flat figures. This means, that the particles have the geometrical shape of a circle, because of all flat figures, the circle has the optimum shape, C/D = pi Also from the theory it ensues that in a state of rest, the gravitational particle mass is described by the formula R/NA = k
The second theory, which describes the vacuum, is "Radiation of an absolute black body". The theory considers an area of space which is located in an absolute temperature balance. This is possible only at T=0K, but it is known that such a condition is called "thermal death". Such a condition does not exist in the nature. Therefore Planck, studying this phenomenon, had come to the conclusion that in order to change such a condition as T=0K, in space where the change is taking place, there should be the radiation of a light quantum having its own internal impulse, h=Et.
Einstein studied this area of science and had come to the conclusion, that there should be a radiation of a light quantum having its own internal impulse, h=kb.
Maxwell’s electromagnetic theory is also connected with the vacuum. His theory considers the electron (an electric charge), which rotates around its own axis, in a local point of the vacuum. This rotation creates an electrical wave. These waves, being in contact with material particles, create an electromagnetic field. Then many physicists (Abraham, Poincare, Lorentz, Einstein and other) were interested in the question, "What will happen to the "rest" electron (Maxwell's) when it moves?" Einstein's SRT arose from this idea.
Einstein's SRT is the fourth theory. This theory describes space in which a gravitational field is not present. Therefore, the theory considers the vacuum at T=0K and the behavior of particles (light quanta) in it. (A desire to link SRT to a gravitational field had brought Einstein to the creation of GRT).
In one of the postulates of SRT is written that the theory considers rectilinear motion of a light quantum in the vacuum with a constant speed. This proves again, that without the vacuum this theory cannot be considered. When the mathematics describe that a certain action in SRT happens in any abstract negative four-dimensional space, it means, that this space is in fact nothing but a real absolute vacuum. From the theory it follows that the quantum of light in a state of rest is described by the formula e/m=c^2. Changes in the rectilinear and equable motion of the quantum of light, which moves with a constant speed, are described by a "Lorentz transformation".
There is one more theory which is inextricably related to the vacuum - quantum physics. This theory asserts that by interacting with the vacuum, an electron has infinite values of mass, charge. The origin of infinite values of electron parameters is connected to its physical and geometrical changes. An electron loses its volume and transforms to a flat circle. In such an interpretation disappears the necessity to use a "method of renormalization", by which mathematicians, as R. Feynman has said, "sweep the dust under a carpet".
Classic physics asserts, that in a vacuum at T=0K, the motion of particles cease. This is fair in relation to the particles with a mass of one proton and above, which move with a low speed. Quantum physics asserts that in a Vacuum at T=0K, there is a constant motion of particles. This is reasonabli in relation to the quantums of light (electrons), which move with the speed of light and higher.
The average density of all matter in the Universe is insignificantly small... approximately
p = 10^-30 g/cm3. The vacuum is the basic substance in the universe. From the vacuum,
this small insignificant amount of matter is born. Physics is first of all vacuum which
is characterized by one simple physical characteristic T=0K.

The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Γαλαξίας (Galaxias), sometimes referred to simply as "the Galaxy"), is a barred spiral galaxy which forms part of the Local Group. Although the Milky Way is but one of billions of galaxies in the universe, the Galaxy has special significance to humanity as it is the home of the Solar system. Democritus (450 BC - 370 BC) was the first known person to claim that the Milky Way consists of distant stars.

The term "milky" originates from the hazy band of white light appearing across the celestial sphere visible from Earth, which comprises stars and other material lying within the galactic plane. The galaxy appears brightest in the direction of Sagittarius, towards the galactic center.

Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of Crux, indicating the high inclination of Earth's equatorial plane and the plane of the ecliptic relative to the galactic plane. The fact that the Milky Way divides the night sky into two roughly equal hemispheres indicates that the solar system lies close to the galactic plane.

The main disk of the Milky Way Galaxy is about 80,000 to 100,000 light years in diameter, about 250-300 thousand light years in circumference, and outside the Galactic core, about 1,000 light years in thickness. It is composed of 200 to 400 billion stars . As a guide to the relative physical scale of the Milky Way, if the galaxy were reduced to 130 km (80 mi) in diameter, the solar system would be a mere 2 mm (0.08 in) in width. The Galactic Halo extends out to 250,000 to 400,000 light years in diameter. As detailed in the Structure section below, new discoveries indicate that the disk extends much farther than previously thought.The Milky Way's absolute magnitude, which cannot be measured directly, is assumed by astronomical convention to be −20.5.
The age of the Galaxy is currently estimated to be about 13.6 billion (109) years, which is nearly as old as the Universe itself.

As of 2005, the Milky Way is thought to comprise a large barred spiral galaxy of Hubble type SBbc (loosely wound barred spiral) with a total mass of about 600-3000 billion solar masses (M☉), comprising 200 to 400 billion stars.



Current measurements suggest the Andromeda Galaxy is approaching us at 300 kilometres per second, and that the Milky Way may collide with it in several (3-4) billion years. If they do collide, it is thought that our sun and other stars will probably not collide with other stars, but merge to form an elliptical-shaped galaxy over the course of about a billion years.

Milkyway is the name of our Galaxy, so it is around us, and we are inside of it.

you're in the milky way (it's our galaxy). If you want to see it, you can look in the sky. You have a few pictures in the wikipedia.
But if you're interested in stargazing, i would recommend mystarslive.com : it can provide you with the sky map taken (calculated) from everywhere in the world at any time you want.
