All About Space
Could there be potential life at our nearest exoplanet, Proxima Centauri b?
yes! The answer is yes. life is complicated, but, at its simplest, the potential for life is synonymous with the potential for liquid water. Wherever there is life on Earth, there is water; wherever there is water on Earth, there is life. Water appears to be not only necessary for life, but a good indication of it as well.
The molecular structure of water gives it a positive side and a negative side.
This helps water dissolve chemicals, group similarly charged compounds and remain liquid through a wider range of temperatures. This, and other attributes, make water greatly conducive to both life and the organic reactions that govern it.
