New research suggests that water can emerge in the universe before scientists – and that can mean that life can also be billions of years.
Water is one of the most important ingredients for life as we know. But exactly when the water appeared for the first time, it has been a question of scientific interest for decades.
Now, new research suggests that there was potentially water existing after 100 million to 200 million years after water Big Bang – Billions of years ago compared to predictions before scientists. This research was published in the Journal on March 3 Nature astronomy.
The early universe was dry because it was basically full of very easy elements, such as hydrogen, helium and lithium. Heavy elements did not develop until the first stars were formed, burned through their fuel supply and eventually burst. Such dark blasts, known as Supernovas, worked like a pressure cooker, which rapidly added light elements to heavy.
“Oxygen, for the formation of water, combined with hydrogen in the hearts of these supernova, pave the way for the creation of the essential elements needed for life,” co -author of the study Daniel WheelinA astronomer at Portsmout University in the UK said in a Description.

To determine that when the water first appeared, the researchers inspected the most ancient supernovas, known as the population III supernovas. Wahlen and his team saw two types of models of these initial star remains: Core Collips Sprinovas, when a large star dropped on its mass. And the pair installation sprinkos, when the interior pressure of a star suddenly falls down, which partially eliminates.
Researchers found that shortly after the Big Bang, the types of both supernova prepared dense flags of gas, potentially water.
Overall, the amount of water in these gas clouds was probably very small – but it was focused in areas where planets and stars were more likely to form. Early galaxies were probably born from these regions, which means that when it was formed, the water was already in the mixture.
“This shows that the terms necessary for the establishment of life were far more than our imagination – this is an important step in our understanding of the early universe,” Wahlin said.
