Scientists have made significant progress in finding the place where the “building blocks of life” are created, where billions of years ago asteroids carried the materials needed to seed life on Earth.
Labor theory Life on Earth is of extraterrestrial origin has been around for a long time and is becoming more widely accepted after a lot of evidence has been consolidated. However, a great mystery remains: Factory “seed of life” What was the beginning, where was it?
A new study led by Dr. Danna Qasim of the Southwest Research Institute (SwRI – USA) and Dr. Christopher Materese of NASA’s Goddard Space Flight Center claims to have discovered this place through environmental experiments simulating interstellar space.

Many previous studies have focused on simulating the formation of amino acids in carbonaceous chondrite meteorite (CC)are a group of meteorites thought to have brought vital materials to planets, including our Earth, and which represent materials from the early solar system.
The new research goes even further back in time, exploring clouds of gas and dust in interstellar space, where the Sun and later planets formed.
“The structure of asteroids comes from the “parent” interstellar molecular cloud, rich in organic matter” – said Dr. Qasim.
Although they did not find direct evidence for the presence of amino acids, they did find precursor organic compounds that were amines. This shows that the material of life was designed from the start “nowhere world” Be Clouds are almost invisibleonly thin gas and dust, wandering among the stars.
To simulate the origin of life, scientists used ammonia, CO2, methanol, water ice… previously identified in interstellar clouds and bombarded them with proton particles of high energy to try to recreate the ice irradiated by cosmic rays.
As a result, ice molecules break down and self-assemble into more complex organic molecules, including amines and amino acids like ethylamine or glycine.
This vital precursor material was supplied to wandering asteroids. Such things took hold on planets like Earth from the earliest stages, providing the first seeds of chemical reactions that gave rise to continued life.
