Is There Really a Galactic Wind Which Controls the Birth of Stars?


We have some interesting news from the flows of gas that appears to be 12 billion light years from Earth –  we now know details about the formation of start from the early days of the universe. There were some powerful winds from the beginning of the universe that were found by scientists for the very first time – and they are 12 billion light years away from our planet. They travel at about 500 miles per second and the scientists believe that this cosmic gas is some kind of a tool that controls the appearance of stars and the galaxies which they belong to.

It’s true that galaxies are complicated, and it’s almost a chaos, but these winds are a crucial thing that shows how they formed and how they developed in time, changing their ability to mature.

The ALMA observatory from the north of Chile was the one which was used by Dr. Spilker and his team to find traces of the winds that date back to the Big Bang (let us remind you the universe was one billion years old at that time).

Even Milky Way has signs of slow, controlled star birth and it’s been shown that only one new star appeared every year. But the thing is that about a thousand of stars can appear in the same space or time in galaxies. They quickly devour the gas ‘tank’ they rely on to make new stars – this is why their life is so short.

The scientist found out that the galaxies try to avoid this death by ejecting big quantities of gas a bit early, a thing that slows down the rate of star formation – this is how the galactic winds are formed.

These patterns are seen in the close galaxies if we are to make the most out of conventional X-ray and some radio techniques.
