Scientists have allowed existence of life on oceanic planets


The group of scientists of the Chicago university has conducted a research and has disproved a hypothesis of impossibility of life on planets which are completely covered with the ocean. Writes Phys.org about it.

was until now considered to be that oceanic planets are lifeless as have no geochemical cycles, characteristic of Earth, necessary for survival of organisms.

These geochemical cycles maintain balance between volcanic outbursts and fixing of atmospheric gases breeds.

However thanks to modeling of several scenarios of changes of temperature and the chemical composition of oceans scientists have found out that these cycles aren't always necessary for existence of life.

So, it was succeeded to find out that many water peace are initially maintained by conditions, favorable and stable for life. For this purpose pressure which is put by the ocean upon crust therefore the metabolism between a cloak and the hydrosphere is complicated suffices.

in general, existence of life on oceanic planets will depend rather on distribution of carbon and other substances between a water cover, the atmosphere and bark.
