Alien worlds resembling giant eyeballs might exist around red dwarf stars, and researchers are now proposing experiments to simulate these distant worlds and see how capable they are of supporting life. When a planet orbits a star very closely, the gravitational pull of the star can force the world to become tidally locked with it. “This means that they always show the same side to their star just as our moon does to the Earth, which means they have one permanent day and one permanent night side” explained Daniel Angerhausen, an astronomer and astrobiologist at Rensselaer Polytechnic Institute and lead author of a new paper on these planets in Astrobiology Magazine.
