According to the panspermia hypothesis, microscopic life—distributed by meteoroids, asteroids and other small Solar System bodies—may exist throughout the Universe. Nonetheless, Earth is the only place in the Universe known to harbor life.

It is the only planet known to have life on it. The Earth formed around 4.5 billion years ago. The large mass of the Sun makes Earth move around it, just as the mass of Earth makes the moon move around it. Earth also turns around in space, so that different parts face the Sun at different times.

Scientists have made a “world first” discovery on a distant planet that hosts both water and temperatures which could support life. Water vapour has been detected on a potentially habitable super-Earth known as K2-18b, located about 110 light years away.

A: Jupiter is a gas giant, which means it probably does not have a solid surface, and the gas it is made up of would be toxic for us. It is also very far from the sun (sunlight can take over an hour to get there) which means that is it very cold.

We may have people making habitats on asteroids I know that humans will colonize the solar system and one day go beyond. Richard Gott has estimated that the human race could survive for another 7.8 million years, but it is not likely to ever colonize other planets.

In terms of life developing on a gas giant? Sure, it’s possible. At best you could have some form of single cell extremophile organism in the uppermost atmosphere. Even this however is unlikely, as Gas Giants are stupidly hot; what their outer atmospheres lack in heat they make up for in cell crushing pressure.

There are layers in the atmosphere of gas giants where the temperature and pressure are inside the limits where life as we know it can exist. It is even possible that larger creatures could evolve, keeping afloat by generating, say, hydrogen as part of their metabolism, keeping it in sacs. A bit like fish on Earth.
