The primitive years of the solar system are wrapped in mystery, but then there could have been life, even when there were no planets?
A scientist suggests the existence of life in the planets
During a conference on breaking up discussions at the University of California, Berkeley on April 11, planetary scholar Lindy Elkins-Tanton of Arizona State University made a suggestion that life may be around before the planets are over.
However, Elkins-Tanton noted
, the planesimals contained all the ingredients necessary for life to flourish in the days when the Solar System was still formed. It is possible that the clinging conditions persisted in these planets for millions and millions of years, allowing life to develop.
Planet planes are building blocks of planets. It is possible that these small objects make their way to the planets like the Earth to pass life that already existed in their burden. Ultimately, the previous research has already suggested that space rocks brought the elements of life on Earth
with the falling of the planet.
"Not all planesimals will be included in the types of catastrophic collisions that will cause them to enter the plasma or otherwise totally deny something that has been created," explained Elkins-Tanton. "Some things will fall – like Chelyabinsk, for example – return to the surface of the moderate planet."
Building blocks of life
Elkins-Tanton, co-author Stephen West, and her ACU students explored the possibility of life stemming from smaller cosmic bodies. All three components of life are present in planesize: liquid water, organic molecules and energy.
For example, radioactive decay
of the particles in the planets, can provide a source of heat that can lead to liquid water and an environment that can be lived within the rocky object. These environments can last millions of years, potentially enough time for life to appear.
Of course, Elkins-Tanton says her team does not claim that life on earth originates from the planets, but simply says there is a possibility. It is, as she describes, a problem with thought that is worth considering, because even the exploration of potential can lead to new insights into the early phases of the solar system.
"Can life really appear on planetary names? Can there be evidence of life in meteorites that we can not search for?" Elkins-Tanton asks. "And if so, how could they spread through the solar system – and many, many unanswered implications of that possibility".
As building blocks of planets, planesimiles are the only cosmic bodies that are of particular interest to scientists like Elkins-Tanton, who also heads the NASA mission for exploring the metal asteroid Psyche, according to
to Scientific American.
NASA's new spacecraft completed
flying the planeside planner Kuiper Belt Ultima Tule in March. This black-preserved rock offers the best opportunity that scientists have ever had to study planesize.
Together with many other features of Ultima Thule
, its surface has evidence of methanol, water ice and organic molecules. The mission could potentially provide an ideal window for astronomers to better understand planet names, and thus to understand early life in the solar system.
