Interesting! You never know. It's a very large galaxy and an immensely endless universe. So to think there's not habitable planets or maybe even life in the universe besides us, would be unrealistic and kind of narcissistic actually.
Astronomers have recently discovered a super-Earth orbiting a red dwarf. And that's not all, because according to their estimates, this exoplanet may have an atmosphere and could be located in its star's habitable zone.
