The Universe is so huge that it's impossible for us to imagine its size. It would take 18 years to fly from the Earth to the Sun, yet this is only a tiny distance in the Universe. Find out how scientists measure the vastness of the Universe, how black holes form, and discover the different constellations on the star maps.
