Astronomers from Columbia University discovered a potential exomoon twice the size of our planet. It revolves around an exoplanet that has a mass similar to Jupiter.
From the moment they were discovered by NASA's Dawn spacecraft, the two bright spots on Ceres have fascinated scientists and amateur astronomers across the world. What are they and why are they there? Scientists believed that once Dawn reached orbit they would be able to learn more about these two mysterious spots, but even now they remain a mystery. NASA has made an unusual move by inviting the public to weigh in on what they believe is the nature of these two bright spots.
The search for life doesn't end at our solar system and it is not limited to just planets. Scientists are now searching for moons orbiting alien planets in other systems that could harbor extraterrestrial life.
