Not with our present technology.
The word for able to sustain life is "viable."
No, so far we have found no life in outer space. Life may well exist in outer space, but we haven't found it yet.
They study how long to get to planets and if there is life in outer space.
The outer planets does not have enough oxygen to sustain life, or they don't have an atmosphere at all.
Astronomy is the study of heavenly bodies.
Because the amount of oxygen in space is not sufficient enough to sustain human life.
Space itself is not considered an ecosystem in the traditional sense, as it lacks the biological components and interactions that define ecosystems on Earth. However, environments like the International Space Station (ISS) can be viewed as micro-ecosystems, where human life and various organisms interact within a controlled environment. In this context, space can host ecosystems, but the vast expanse of outer space remains largely inhospitable and devoid of life as we know it.
Ecosystem. APEX :P
People cannot live in outer space because it lacks the necessary elements to sustain human life such as air, water, food, and protection from radiation. Without these essentials, humans cannot survive in the extreme conditions of space.
Exobiology.
Exobiology, is ths study of phenomena occurring in the upper atmosphere or celestial objects in outer space.
It is impossible to know at our stage of development. Humans today can only see a small part of space. Maybe one day human or robots can adventure into space and possible find life in outer space.
