The various shapes of the Moon shows in the sky came to known as the Moon phases. Due to its position relatively to the Earth, the phases change from New Moon (when no Moon is visible), to Waxing Crescent, to First Quarter, to Full Moon (when the entire face of the Moon is visible). Galileo Galilei was the first person to turn the telescope towards the Moon and immediately realised the wonderful three-dimensional details of its surface - the valleys and peaks, the areas with shadows and the illuminated areas. Galileo studied how the light hit the Moon and the way the shadows moved across the surface unevenly at the line where the lighted half of the Moon met the dark half. No, the Moon was not smooth or perfectly round!Moon Moon phases astronomy Solar System rotation movement translation movementLOM v1.0final1.0LOM v1.0author2009-01-01Leonor CabralPaula FurtadoLOM v1.0publisher2013-04-04Leonor CabralenLOM v1.0LOM v1.0creator2013-06-10Leonor.CabralLOM v1.0validator2013-06-10Ana CostaLOM v1.0browserLOM v1.0anyLOM v1.0osLOM v1.0anytext/htmlhttp://portal.discoverthecosmos.eu/node/195740LOM v1.0noLOM v1.0noLOM v1.0mixedLOM v1.0very highLOM v1.0mediumLOM v1.0Inquiry-Based TeachingLOM v1.02 didactic hours9-1212-15LOM v1.0DisciplineScienceAstronomy: EarthAstronomy: MoonAstronomy: OrbitAstronomy: Phases of the MoonAstronomy: PlanetsAstronomy: Solar systemAstronomy: Solar system - otherAstronomy: SunScientific enquiry: Creativity in scienceUseful materials and products: Everyday materials
