The solar system - the old place. He is 4.6 billion years, to be exact. However, the solar system is much younger than the universe, which is 13.8 billion years, plus or minus a couple of hundred million. $ CUT $ turns out, the universe is three times older than the solar system.

Astronomers believe that the Milky Way about 13.2 billion years old; Galaxy is almost as old as the universe itself. It was formed when small dwarf galaxies merged to form a grand spiral, as we know. 8.6 billion years the Milky Way just fall out of focus. Gone are billions of years before the solar system was able to assess the situation.

Milky Way
Our galaxy rotates once every 220 million years, so in total it has done it about 60 times. As the rotation of the galaxy, it sucks the material, like a giant cosmic vortex. Clouds of gas and dust are collected together in a giant star-forming regions, massive stars become supernovae and then clusters are broken again, sending the stars in the Milky Way. This occurs in the spiral arms of the galaxy, where the dense star-forming regions.

So back to 4.6 billion years ago, before there was Earth, the Sun, and even the solar system. All our region gas and dust, possibly in one of the spiral arms. What it was like? The Hubble Space Telescope took these pictures for you

This is the Orion Nebula, the Eagle and the Tarantula. This star-forming region. They are represented by clouds of hydrogen remaining after the Big Bang, dust scattered aging stars and planted in heavy elements formed in supernovae.

The Orion Nebula
After a few million years of high-density regions of the stars begin to form, large and small. Let's again look at the star-forming nebula. You see dark spots? This newly formed stars surrounded by gas and dust in stellar nurseries.

You see a lot of stars, large and small, similar to our Sun and red dwarfs. Most of them will soon be the world - and possibly life. Where is she? What's wrong in this picture, where other stars, our brothers and sisters?

Nebula

Apparently, nature does not like trouble and star cozy nest. The nebula that gave birth to the sun, the stars were either absorbed or its powerful stellar winds blew larger stars. Eventually, haziness disappeared as a cloud of smoke from the cigarette.

From the very beginning, our nebula is somewhat reminiscent of the Eagle Nebula, after millions of years it has become more similar to the Pleiades where bright stars nebula surrounds shaky. The gravitational forces of the Milky Way ripped members of our solar creches to structures like the Hyades. Eventually, the gravitational interaction between the cluster and tear, and our kinship the stars were lost forever in rotating arms of the Milky Way.

We will never know with precision what was there before the solar system; Evidence of this was long ago lost in space. But we can see other places in the Milky Way, which give us a rough idea of how it might look like in different stages of development.

But she could be called Nebula, which came our star?
