Starlight - Keith Robinson Size:EN STL Jupiters fyra galileiska månar synsWhen you look up at the sky at night and see the stars, do you understand what youre looking at? What is starlight made up of, and how does it travel to us? How are stars born, and how do they die? How do we figure out how far away are the stars and how massive they are? Can we know which stars will go supernova and which will end up as white dwarfs or black holes? How long will our Sun continue to shine down on us, and how do we know its age?
