Researchers have suggested that the search for alien life should go beyond looking for Earth-like worlds.
So far our efforts have been focused on locating planets that exhibit similar conditions to that of the Earth, but what is to say that all life forms require an earth-like environment ? While seeking planets hospitable to humans is a good strategy, planets that might seem completely hostile to life as we know it should not be ruled out.
When searching for alien planets that could host extraterrestrial life, scientists should broaden their minds beyond "Earth-like planets," researchers say.
