Interesting Facts on Milky Way

"Why Milky Way Special To Us"

Andromeda Galaxy

A misty band of light spread across the night sky is called as Milky Way,the galaxy in which we live.The Sun and its planets,including our earth lie in this quiet part of the galaxy,about half way out from the center of the Milky Way.

The Milky Way is shaped like a huge whirlpool or spiral 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 1,00,000 years to cross from one side to the other!

The center of galaxy is very hard to see because clouds of gas and dust block our view.Scientists think that it contains a super massive black hole that swallows anything passing too close.

The Milky Way was born when countless warm gas clouds came together under the pull of gravity.When the clouds collided,stars were born.Nine billion years after its birth,the Milky Way is settled down.There is a huge black hole at its center,but it is quiet.The Galaxy now consists of billions of stars arranged in a beautiful spiral shape.

The oldest star in the Milky Way is the one named as HE1327-2326.It is located 4000 light years away from the earth.
