Usually, scientists are looking for life on other planets like ours. But there is a possibility that a new location will appear for the search. The latter study indicates that there may be more than 121 places where we should look for signs of life. But this is not about earth-like planets. Now focus on the moons!
Satellites from planets, like Jupiter and Saturn, are great places to search. Why not? Even our own Moon can one day take a human life. Researchers have long been thinking about Europe (satellite of Jupiter). There is a lot of evidence indicating that liquid water is present on a tiny satellite.
Location, location and location again
Agree that finding life in a large-scale space is really a difficult thing. Therefore, first decided to find out how many potentially lively moons exist. Attention was also focused on the habitat zone, where the temperature allows liquid water to exist on the surface. The data was analyzed from the NASA Kepler mission, which was launched in 2009. She is now studying the Milky Way to search for potentially inhabitable planets. So far we have little information about how many satellites are in the zone where the stars live, like our Sun. But we know that there are many around the giant planets (Jupiter - 69 moons, and Saturn - 62).
If we find the exact number of suitable planets, then we can go to their satellites. The study leads approximately 121 giant planets located within the habitat zone of the Milky Way galaxy. They are able to have the moons necessary for life.
If we assume that large planets have several satellites, then this increases the number of potentially inhabited worlds that can be monitored. The problem so far is in the invention of the method of searching for life (microbial or higher intelligence). Scientists plan to continue the hunt for the most interesting for the study of satellites and planets that can shelter life.
