A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

A new study suggests that the origin of Pluto's largest moon was quite different than our own. Here's what you need to know.

New models reveal Pluto and Charon may have spent some of their early history locked together in an embrace after a grazing ...

Simulations suggest Pluto and its largest moon may have gently stuck together for a few hours before Charon settled into a ...

Throughout January, four planets will line up in the night sky and be simultaneously visible to the naked eye in the Northern Hemisphere. Our celestial neighbours Venus and Mars as well as big ...
