Age of the Sun is only about 4.57 billion years old. In other words, it appeared much later formation of our Milky Way galaxy. But if you were on the planet 10 billion years ago, when our galaxy was relatively young, then when you look at the night sky, it would look very different compared to how it looks now.

Night sky would look about the same as shown in the artistic representation above, where we can see a young Milky Way galaxy, as if we were on the ground, which already existed 10 billion years ago.



"You can see the bright flashes of the birth of new stars, and pink clouds of gas and dust surrounding a young star clusters", - explained in the NASA.

New studies of young galaxies belonging to the same type as ours, show that the formation of new stars such galaxies eventually slow down its rotation. And scientists at NASA have that explanation:

"Astronomers do not have access to images of a young Milky Way galaxy, so the only possible way to learn about how it could look like in its early years, is the observation of the young and like the Milky Way spiral galaxies detected thanks to many years of deep space exploration using the most advanced telescopes and technology. "

"The more scientists look into the Universe, the more they come back in time, as the light from distant, very distant stars are only now beginning to reach our planet. These studies of light over the age of 10 billion years, scientists have been able to create a photo album containing nearly 2,000 images of galaxies similar to our own Milky Way. "

"The information obtained gives scientists the most comprehensive to date understanding of how over the last 10 billion years formed our amazing spiral galaxy. This is an incredible large-scale study includes observation of the cosmos from the ultraviolet to the far infrared spectrum, which is complemented by observations of space observatories NASA «Hubble" and "Spitzer" information from the Herschel Space Observatory of the European Space Agency, as well as many ground-based telescopes, including the Magellan Telescopes located in Las Campanas Observatory in Chile.
