Human blood comes from aliens

A recent study by American scientists revealed that iron in human blood could come from other galaxies from billions of years ago.

A team of astronomers from the US has just published a new study revealing how the universe formed heavy metals (such as iron).

According to this study, this series of events takes place about 10 billion years before the age of the universe is equal to one third of the current, not iron is formed after having Earth as many people think.

The study was managed by experts at the Kavli Institute of Space and Astronomy (KIPAC), in conjunction with the Energy Agency of the National Accelerator Laboratory (SLAC) and Stanford University (USA). Head of research is the astrophysicist of KIPAC - Mr. Norbert Werner.

The team's most important discovery is that the exploding stars themselves (such as supernovae, meteors) and black holes have 'sown' heavy metals and are unevenly distributed across 190 galaxies .

This finding reinforces the hypothesis that, about 10 billion years ago, the universe was very unusual and powerful. Without that period, life on Earth could not be formed.

Iron and many other heavy metals existed between galaxies long before the constellation of the English Fairy (Perseus) began to form. Most of the chemicals are created by billions of giant stars that exploded not long after the Big Bang.

Basically, every short-lived star is a reactor. Scientists believe that the same process takes place in most black holes in galactic cores.

Ondrej Urban, a graduate student at KIPAC, said: 'The combination of the energies of these cosmic phenomena must be strong enough to push the metals out of the galaxy and get rich, mixing the intergalactic gas.'

When conducting the research, the team also calculated the amount of iron in the constellation of Fairy English, equivalent to the total amount of iron that exists in the . 50 billion solar universe.

Aurora Simionescu, Japan Space Exploration Agency, co-author of the study, said: ' Human blood iron is much older than scientists calculate. They formed in the universe billions of years ago and millions of light years from Earth '.

It is known that this study uses data collected by Suzaku (US-Japan) satellite. The work has just been published in Nature on October 31
