Water could have been formed for the first time between 100 and 200 million years after the Big Bang, that is, before what was thought, and could be a key constituent of the first galaxies, according to a study that publishes Nature Astronomy.
A team headed by Daniel Whamen, from the University of Portsmouth (United Kingdom), used two supernova computer models: one for a 13 -time star and the second star for a 200 -time star, to analyze the products of their explosions.
The water, primary ingredient for life, “existed even before the construction blocks of our own galaxy were formed,” said Muhammad Latif, from the United Arab Emirates University and one of the signatories of the investigation.
The simulations, in addition to relieving that the water would already exist in the universe between 100 and 200 million years after the Big Bang, they show that it was probably a key constituent of the first galaxies, the study indicates.
Water components (hydrogen and oxygen) are known to be formed in different ways. The lighter chemical elements, such as hydrogen, helium and lithium, were forged in the Big Bang, but the heaviest, such as oxygen, are the result of nuclear reactions inside stars or supernovas explosions.

The researchers discovered that in the first and second simulation 0.051 and 55 solar masses were created (where a solar mass is the mass of our sun) oxygen, respectively, due to the very high temperatures and densities reached.
When that gaseous oxygen cooled and mixed with the surrounding hydrogen left by the supernovae, water could form in gaseous state -in the form of vapors -that would accumulate mainly in the form of an disk.
These dense water centers “are potential hosts of protoplanetary discs that could even lead to the formation of habitable planets in cosmic dawn,” according to Latif.
The radiation of the posterior star formation could destroy that water, but it would also be possible for the stellar dust to protect it from such radiation. “This is something that we are going to explore in future works.”
In the first simulation, the authors verified that the mass of water reached equivalent amounts approximately one hundredth or millionth of a solar mass between 30 and 90 million years after the Supernova.
In the second, the amount of water reached approximately 0.001 solar masses after 3 million years.
