Looking for life beyond the solar system, we first look for the closest star systems with land -like planets. Here’s why that is not good enough.
When it comes to finding life in the universe, there is still a place we know that has it: here on planet Earth. However, as science has recently shown us, both the raw ingredients necessary for life, as well as the necessary conditions for life to bloom, are very omnipresent throughout the universe, even here in our own Milky Way. The Earth can be very special in the sense that we, an intelligent civilization, which uses tools and technologically, we have emerged in it, but for almost the whole history of our planet, we were still an inhabited planet where life arose, survived and survived and He survived and survived and survived and survived since then.
However, a key ingredient that is believed to be necessary for life is liquid water. All living organisms here on earth trust it, even those that live in the most extreme conditions (dry, hot, volcanic, high pressure, etc.). Until now, there are only two main forms that are known to have liquid water on a planet or planetary body:
- You can lower under the surface until there is enough pressure, heat and (potentially) salinity for water …
