Europa is one of Jupiter's largest moons.

HistoryEdit

Europa was discovered on January 7th, 1610 by Galileo Galilei.

LifeEdit

Europa is thought to have the right conditions to support life as we know it beneath its surface. Europa contains about twice the amount of water there is on Earth, hidden below it's icy surface. Also, it has an atmosphere of oxygen, which is essential for life as we know it. Hot underwater springs could supply the heat and energy needed for life to live in.

TriviaEdit

  • Europa is the smallest Galilean Moon of Jupiter.
  • The Jupiter Icy Moon Explorer is planned to make a few flybys of Europa, but the mission is mainly focused on Ganymede.
