Science competition | Is there alien life in the solar system?

Questions:

1. This moon of Jupiter is the most geologically active planetary body in the solar system, which makes life on this body very unlikely — but not impossible, especially since all that activity keeps it quite warm. The name of this moon.

2. Data collected in 2015-2018 suggest that the largest asteroid in the solar system may contain a large subsurface ocean of water, but the evidence is weak. Highly saline water is still expected to flow to its surface and may contain microbial life. Name this asteroid.

3. This moon is the only planetary body in the solar system other than the Earth that has a complete circulation of liquid on its surface. On Earth, it is made of water. This moon has hydrocarbons, which represents the potential to host life. Moon name.

4. This moon of Neptune has a mysterious feature: it is the only moon in the solar system that rotates in the opposite direction to that of its host planet. Scientists expect that radioactive decay of rocks in the interior of this moon will release enough heat to maintain its atmosphere of water in a liquid state, increasing the possibility of life. Moon name.

5. NASA spacecraft found that this moon of Saturn may contain an underground water ocean. The Moon also shoots plumes from beneath the surface through the icy crust into space, which contain salty water and organic molecules, indicating the possibility of life. Moon name.
