Milky Way
 =Galaxies =

The galaxy is a massive, gravitationally bound system that consist of stars and stellar remnants , and instellar medium of gas and dust , an important but poorly understoood componet tentativey dubbed dark matter. the name is from the greek root ( galaxies ] meaning " Milky", is a reference to the Milky Way Galaxy . The sun is one of the stars win the Milky Way Galaxy ; The solar system includes the earth and all the other objects that orbit the sun . A common form is elliptcal galaxy , whuch has a ellipse shape light profile. Spiral Galaxies are disk-shaped assemblages with dusty, curving arms . Galaxies with irregular or unusual shapes are known as Pecuilar galaxies , and typically result from disruption by the gravitational pull of neighboring galaxies. Such interactions between nearby galaxies, which may ultimately result in galaxies merging, may induce episodes of significantly increased star formation producing what is called a starburst galaxy. Small galaxies that lack a coherent structure could also be referred to as irregular galaxies.

= Milky Way = The milky way, or simply galaxy in which our solar system is located is the barral sprial galaxy that id part if the local group of galaxies. It is pne of the billion of galaxies in the observation universe. NGC 4414 ( Milky Way ] began it journey to the earth around 62 million years ago . The universe galaxies come in many shapes, sizes, and colors. Most of the larger ones are sprial galaxies like our own . Most galaxies spin through space in a peacful isolation from on another . The milky Way passes through some of the brillant constellation : Cassiopeia, Cygpus, Perseus, Auria , and Aquila in the northern hemisphere ; and Buppis , Vela, Carina, Crux , Centaurus, Scoripus , and Sagititarus in the southern hemisphere . The width of the Milky Way varies greatly in places. it is only about 5 degrees across while others are 30 degrees . The Milky Way holds at least 100 - 400 billion stars . The oldest star is about 13.2 billion years old.

Scientists now estimate that in roughly three billion years, the Milky Way galaxy will actually collide with the Andromeda Galaxy, which is very slowly working its way towards us at a modest speed of about 1,800 kilometers per minute.  <span style="background-color: #000000; color: #800080; display: block; font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif; font-size: 110%; text-align: center;">weblinks.
