It has come to my attention through observation that
the proposed theory of a planetary hospitable zone is infact false. By observing the various species of
life on our planet it is difficult to except the theory of a sole hospitable zone in which life in another star system can exist. As an example we can use the life form known as Ice plankton which manages to survive in one of the coldest regions of our planet, the North Pole. This proves that even if a planetary system contanined a planet outside of the hospitable zone, further away from it's sun, and had the essential water necessary to aid in the production of life then a hospitable zone as proposed becomes negligible. The same can be summized when observing life that exists in a desert environment where water is scarce. Life forms are able to adapt, and survive in these harsh environments. Although our science today is in the search for intelligent life it is of wonder how many planets that could exist in the universe that has what I would like to refer to as intelligent life in it's infancy. This would be similiar to animal, plant, or insect life that exist on our world. These creatures as we know do not have the capability of communicating in an interstellar environment as far as we know. The only way this would be possible is if they have had contact with intelligent life similar to there own species that do infact have intelligence, and are of a higher intelligence than mankind. These life forms could infact blend into the animal, plant or insect environment on our world with out detection do to there evasive manuevers to avoid human contact. We know this from the traits of many species on our planet who do avoid contact with humans as a defence mechanism. If this is the case then more research is neccessary in order to explore the communications process between man and the other life forms on our world to find links, and possibly find a lanquage structures that other life forms on other worlds might be able to relate to.

I assume that you're referring to the region which is a proper distance from the sun to support life as we know it. For us, this region spans from Venus to Mars. The habitable/hospitable zones is an area that is capable of supporting liquid water as it is related to solar radiation. NASA is fully aware of what you're saying.

For example, they are doing or have done artic experiments to determine the best way to explore beneath ice beds for life. How far do they need to penetrate? What detection methods can be used to rule out life? What detection methods can be used to confirm life? Once they have it figured out they can send a probe to Europa to probe for life because they think that the tidal forces from Jupiter might be strong enough to generate the heat to maintain oceans of liquid water beneath the ice. The significance of water is that chemistry needs a solvent and water is perfect for the temperature ranges needed to accomplish this chemistry.
Europe tells US: 'Come to Europa'

For the upper limit of life. Life is confirmed upto 110 deg and 120 deg although the 120 deg might not be a sustained temperature. This life consists of microbes along the oceanic faults which spew hot sulfer and such. It's thought that the true upper limit is around 150 deg, beyond this degredation becomes to great to maintain life.

With that, it's improbable that life exists on Mercury or Venus but is likely on Mars and various moons like Europa.
