Germany Celebrates World Cup Victory

  An extra-time goal gave Germany a win Sunday over Argentina and the World Cup title.
    
Midfielder Mario Goetze scored the game-winning goal.
    
Germany's victory was celebrated by fans around the world and even in outer-space.
    
German astronaut Alexander Gerst congratulated the team from the International Space Station on its "top performance."
    
He tweeted a picture of himself in a Germany Jersey with an extra fourth star, saying, "As experts on stars, we already got one."
    
It's Germany's first World Cup title as a reunited nation.
