It’s an exciting year in space exploration as Ceres is now being investigated and Pluto will be seen for the first time in July. These may also be the last large objects to be explored in the solar system for a very long time. But not to worry, the only other large objects are quite far away, though I’d love to see Eris and Haumea especially.
However, part of what makes Ceres exciting is the prospect of life, or the small possibility of it being habitable by very marginalised life. There are several candidates in the solar system that have the potential to support life:
- Mars is quite promising, but mainly in the past.
- Ceres needs to be examined more first.
- Europa has liquid water oceans.
- Titan is a very different world, but has conditions similar to early Earth.
- Enceladus also likely has liquid water under the surface.
These five are of particular interest at the moment. Which world do you think is most likely to support life? Vote in the poll below and leave a comment explaining your choice. I’ll make a post later on examining each of these worlds and making my own conclusion.
