As of 2015, the planet Uranus cannot support life as it is known on Earth. However, it is not impossible for this ice giant to sustain other life forms that can withstand its harsh environmental conditions, which are vastly different from those on Earth.
For another planet to host the carbon-based living organisms on Earth, certain prerequisites must be met. These include a habitable zone, protective atmosphere, rocky surface and molten core.
Uranus is a massive icy ball of methane, water and ammonia. Although it has an atmosphere, the lack of a solid surface signifies the absence of nutritive components to provide the vital energy that drives essential life processes. Even if the planet contains a rocky core as some scientists suspect, the tremendous pressures and temperatures inside Uranus would crush terrestrial life forms.
