**The Milky Way**
If you didn't know already, The Milky Way, which holds more than 400 billion stars, is the most known galaxy out of the tens of billions in this universe. It is also the home to our solar system. There is a Greek Mythology about baby Hercules who was brought by Zeus to drink Hera's breast milk so he can become immortal. What we see in the night sky is spilt milk. The Milky Way appeared like a ribbon of milk to the ancient Greeks and the word //galactos// is the Greek translation for milk. Galileo used his telescope to prove that the light of the galaxy comes from the billions of stars in the galaxy which forms the milk.

It's almost as if we lived in galactic "burbs", just sitting on the outskirts of a giant. With the Milky Way Stretching 100,000-120,000 light years in diameter, it has been estimated to have a 750 Billion to one trillion solar masses. Astronomers have used Kepler's third law to help calculate the mass of the Milky Way. The way they did this was to relate to the orbit radius and period with central mass. "It was the Greek Democritus (460-370 BC) who first claimed that the Milky Way consisted of distant stars. William Herschel, in 1785, made the first map of the Milky Way. Herschel was the first to study and measure the distribution of stars in space. He counted the stars he could see and concluded that the stars were grouped into a huge disk formation and he was right." If we viewed this **[|Spiral Galaxy]**, so named for its spectacular **[|spiral arms]**, on its side we would see it as a flat disk with a bulge in the center. The entire disk has an angelic halo where most of the bright stars live. The Milky Way arms are named for constellations and the major arms of the Milky Way Galaxy are called Perseus Arm, Sagittarius Arm, Centarus Arm and Cygnus Arm, they are located out towards the edge of the Milky Way on one of its spiral minor arms called the Orion Spur. The central bulge consists of old stars and at least one black hole. The arms contain younger stars with dust and gas which form from new stars. How old is the milky way exactly? With having an estimate of the age of the universe, we can be sure that the Milky Way is younger. The Milky Way galaxy is range 800 million to 13.5 billion years old.

Our sun is located in the disk about 28,000 light-years from the galactic center. It took scientists up until the recent century to prove that our sun is not the center of the galaxy but it does revolve around it. The sun does a circular orbit with the speed of about 220 km/s. The sun completes a revolution in about 230 million years. While the sun is orbiting around the Milky Way, the Milky Way is also moving. We found that the Milky Way actually moves towards it's neighbor, the Andromeda galaxy. The center of the Milky Way galaxy is about 200 **__[|globular clusters]__**. Part of the problem is that clouds of interstellar gas and dust known collectively as the **[|interstellar medium]**fill the galactic disk. This makes it hard to see. There is dust and smog, which also makes it difficult to see when astronomers try to observe it in visible light. As a result, it is hard to discern that we don't live near our galaxy's center.

 * Summary:** The Milky Way is a sprial galaxy. It carries three major components: The halo, the nuclear bulge and galactic center, and the disk. Each one of the three compnonets have something important about them. The halo consists of old stars. It is also filled with hot, highly-ionized gas. The nuclear buldge and galactic center is fairly crowded. What shows to be in the center of the Milky Way is a young supernova remnant on the east, ionized hydrogen on the west, and a source called Sagittarius A* in the center. And lastly, the disk. The disk of the galaxy is flat and rotates fairly close to the sun and several young stars.

 * Author:** Unknown (appers to be owned by a Astro101 class)
 * Overview:** This webpage gives great insite as to how certain things about the Milky Way were undiscovered long ago in the 20th century. "The globular clusters were one of the keys in the research that revealed the size and shape of the Milky Way galaxy. Another key is variable stars, which reveal their intrinsic brightness by the rate at which they vary. The astronomer who used the keys was Harlow Shapley. From his measurements of the distance to variable stars in globular clusters, Shapley could see that the clusters were not evenly distributed around our solar system, thus inferring that our Sun is not in the center of the galaxy. The globulars are distributed and orbiting around a central point 30,000 light years in the direction of Sagittarius, a point we now accept as the galactic core. At that time, (early 20th century), most astronomers still thought that the Milky Way was the whole of the Universe".

[] "We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.The Milky Way is shaped like a huge whirlpool that rotates once every 200 million years. It is made up of at least 100 billion stars, as well as dust and gas. It is so big that light takes 100,000 years to cross from one side to the other."
