Enceladus's ice ocean was similar to that of the earth.

Enceladus was discovered in 1789 by astronomer William Herschel, but for many years remained

unexplored. The first reliable data on the cosmic body were obtained from Voyager probes 1 and 2, and in 2005 the Cassini-Huygens mission began studying the satellite Saturn.

Water from the under-ice Ocean Enceladus is released to the surface by powerful geysers - now researchers have found out that it is rich in carbon dioxide and in terms of acidity is close to the oceans on Earth.

After analyzing the Cassini probe data, astronomersconcluded that his images of the ice surface did not provide an accurate picture of the composition of the under-ice ocean. Scientists believe that rising to the surface, the water functions - this leads to the fact that light substances are released more often than heavy ones. This researchers explain the fact that the similarity of the oceans of Jupiter’s satellite and the Earth’s has not yet been discovered.

Earlier, the Breakthrough Starshot Foundation, owned by Russian entrepreneur Yuri Milner, agreed with NASA to jointly launch a research vehicle to Saturn’s satellite Enceladus.
