Were an intergalactic traveler to approach the Milky Way edge-on, the first thing she would notice is a luminous halo made up of gas and stars enveloping the galaxy.
According to one hypothesis, the strange warp in the Milky Way's hydrogen disk is caused by the movement of two dwarf galaxies-the Large and Small Magellanic Clouds- and their interactions with dark matter as they orbit our galaxy.
The Milky Way is believed to contain four major spiral arms, all of which start at the galaxy's center, plus a number of smaller arms.

Practically everything we see with the unaided eye in the night sky is a part of the Milky Way, except for a few visible extragalactic objects such as M31, the Andromeda galaxy.
The Milky Way is an island of hundreds of billions of stars, gas, and dust held together by gravity to form a gigantic disk that is surrounded by a halo of globular clusters, which are smaller spherical groups of stars.
Studying the way in which the stars orbit gives details of the gravitational field of the Galaxy and ultimately reveals its mass.

On the other hand, the amount of matter between a star orbiting the Milky Way galaxy and the center of the galaxy steadily increases the farther you go from the center.
Galaxies like the Milky Way are about 10 billion years old, so any pattern established when the galaxy came into existence should have long ago disappeared.

The galactic collision between the Milky Way and the dwarf galaxy, named Canis Major after the constellation it is found in, has so far been obscured by dust in the dense disk of the Milky Way.
The M-giants were used as beacons to trace the shape and locality of Canis Major and to provide a three-dimensional structure of the distant regions of the Milky Way.
While astronomers have long suspected that the central part of large galaxies like the Milky Way were built up by swallowing up satellite galaxies that came too close, this is the first time that the outer region — or disk — of a galaxy has been seen doing the same thing.

 Discovery Channel :: News :: Study: Milky Way Is Tentacled Beast
Using data from a painstaking galaxy-wide survey of hydrogen gas clouds throughout the Milky Way, radio astronomers found that instead of being a clean, symmetrical spiral, our home galaxy has extra long arms sprouting out on one side and is warped and armless on the other.
Blitz co-authored a paper on the newfound shape of the Milky Way with graduate student Evan Levine in the June 1 edition of Science Express.
Another possibility is that the bulge is caused by the gravitational tug of the Milky Way’s small satellite galaxies.
