Is Earth alone in the universe? Scientists have found planets that might just host alien life. Let’s explore the most promising ones!
1
Located 1,400 light-years away, Kepler-452b orbits in the habitable zone of a Sun-like star. Conditions could support water and life.
2
This planet lies in a system of 7 Earth-sized planets. TRAPPIST-1e may have the right temperature and atmosphere for alien life.
3
Just 4.2 light-years away, Proxima b orbits a red dwarf. It may have liquid water—making it one of the top alien life candidates.
4
Though debated, Gliese 581g could have a stable climate and surface temperatures that allow water—a key to alien life.
5
Not a planet, but this icy moon shoots water plumes into space—hints of an underground ocean that may support microbial life.
The search for alien life is just beginning. These places spark hope that we may not be alone after all!
