Astronomers might have discovered a moon orbiting an unknown rogue planet. Although the planet does not orbit a star it may have a moon similar to Earth's size and be warm enough to contain liquid water, which is essential for life as we know.

Mary Anne Limbach from Texas A&M University, along with her colleagues, performed a series calculations to determine if rogue planets could be good places for looking for moons outside our solar system.
