Jupiter's moon Europa is now ready as NASA team prepares to make a big announcement and reveals the discovery of the unusual activity on the icy moon as it claimed that NASA had happened upon an "alien homeland" on the distant world.

Europa belongs to the largest of Jupiter's moon, and to count all; Jupiter has 67 known moons. And as reported from the Tribune India, since 2013, the Hubble Telescope observed water vapor that is erupting from Europa, that resulted in a tremendously exciting discovery.

Also, Europa contains huge global ocean which is proven to provide twice as much water as the Earth's oceans, somehow protected by layers of glacial and hard ice of unknown thickness.

As The Sun reported, it is likely the discovery that relates to an ocean beneath Europa's crisp crust. On the other hand, ET hunters should still have cause for excitement, because there's every chance this water could be home to alien life forms, although further missions will be needed to find this out.

The research for Jupiter and its moons, including Europa started in 1989 as NASA launched Galileo to find proofs of life in the alien homeland. The mission lasted for 14 years, and now it has earned substantial evidence describing its physical features such as the size of its moon and the unknown thickness of the ocean beneath the frozen crust.

"Now is our chance," Mr. Grunsfeld said during a workshop held at the Ames Research Centre in California. "I just hope we don't miss this opportunity for lack of ideas."

"With abundant salt water, a rocky sea floor, and the energy and chemistry provided by tidal heating, Europa could be the best place in the solar system to look for present day life beyond our home planet," NASA said in the last year's interview.
