Humans have often wondered if there might be extraterrestrial life in space and when we might get in contact with them. Although we have not found alien life yet, we have narrowed down the list to where in space they will likely be from.
Scientists have examined the features of numerous planets and moons in our solar system. They looked at different attributes such as water, atmosphere and chemical compositions. After looking over these features, scientists know for sure which places in the solar system are the likeliest destinations of alien life. However, scientists still don't know if these places can sustain life. There will have to be more research.
In addition to the nearby planets, scientists are looking beyond our solar system. They are examining exoplanets that might be in or near the habitual zone where life can be sustained under the right circumstances.
There are some scientists who believe that it is not likely that we will find intelligent life forms outside of our solar system. However, technology has shown that there are Earth-like planets beyond our solar system. Many of these exoplanets have the potential for life. On the other hand, some of these planets might not have all of the conditions to sustain life. It might take some time before scientists can fully focus on these issues.
Which planets and moons are the ones that could likely have aliens? Here are 20 of the best examples in science. Did you know about any of these?
