Some five billion years from now, alleges Carl Sagan , there will be a last, perfect day on Earth... then the sun will slowly change and the Earth will die.
Tonight we see that all heavenly bodies are fated to be born, live and die.
On our planet, we're told, finally the oceans will boil and evaporate and our atmosphere will gush away to space...
