Question

If biotic origin of life is in progress on a planet other than earth what should be the condition there

Answer 1

Thanks for the question!

It is definitely a very interesting question to solve and do some brainstorming.

**************************************************
Biotic processes and the origin of life through Biotic means on planets other than Earth should be habitable or a criteria which is fulfilling to colonise the planet, are:

The main requirement will the the fulfillment of oxygen enriched planet with protective layers for harmful radiations like Ultraviolet rays, Ozone, etc. Protective atmosphere would be a second requirement which will have abundance in some major gases and minority in lower most gases or gases with less importance to make the planet under a optimum temperature and a perfect warmth for the Biotic living beings (or Aliens).

There should be a presence of proper layers or levels of establishing a correct planet, that is, the presence of molten core to provide geothermal energy extraction and allowing the extraction of mineral resources and molten rocks of equal importance or removing of raw materials should be possible. Magnetic field should govern the planet for protection against harmful radiations and to maintain buoyancy. Molten core should be in a solid state, if it is in liquid state then it will not be claimed as a stable planet for life to occur or for colonisation, as, the heat produced will escape and dissipate extremely fast, making the temperature to go bouncers.

Distance between the main star and the obituary planet bodies should be very close or equivalent to that of our distance between the sun and earth. If it crosses those limit under the upper and lower extremities, it will surely miss out an exact level of providing of temperature control. As a result, the planet body should not be too far from the main star, as, it will cross the lower extremity and cause coldness throughout the region, and, it should not be too close, as, the higher extremity will come into play and cause extreme hotness, in either ways it will be unable to reside into it. The habitable zone should be just about right zone to colonise, not too far, not too close, neutrality will be the subject here.

The plate tectonics which are supporting the planet other than Earth should get a constant change or make the topmost and innermost layer recycling throughout a period of time. This will ensure the level of carbon dioxide to be exact, not too high or low. Nevertheless if it exceeds the amount it will cause the greenhouse effect making the planet too hot to colonise for or other life forms to exist. This will simply mean the liquid water will not be for too long and will evaporate quickly and the whole planet dries up making it impossible to survive. Moreover if the levels of it become too low it will mean the planet will be dead cold making again unable to survive. The motion of the plate tectonics will ensure that there is neither of the two extremities coming into the act.

Last and finally the only condition to have a second life in another planet is the availability of rocks found to be in abundance in the planet throughout the planetary regions. Absence of rocks and microbial life will mean that only gases are making up the matter and there is no chance for having colonisation and habitable criterion for planets.
