The ocean of Europe turned out to be more similar to the Earth’s than previously thought.

When the Voyager and Galileo spacecraft, which explored Europa, sent data on signs to Earth

the presence of an ocean on Jupiter’s satellite, this inspiredScientists have hope for the existence of life on Europa. However, a more detailed study showed that water ice on the surface of the cosmic body contains traces of magnesium sulfate salts - or Espom salts.

Since Europa's crust is young withIn geological terms, this meant that salts could rise from the ocean below the surface, greatly reducing the likelihood of life there.

Now scientists using a spectrograph,installed at the Keck Observatory in Hawaii, again analyzed the composition of water ice on the surface of Europa. The study showed that magnesium sulfate salts disappeared from the surface of the satellite.

Scientists checked the data obtained withusing the Hubble telescope, which performed a spectral scan of the surface of the cosmic body in the visible range at 450 nm and confirmed the absence of matter.

The discovery means that Europa's ocean is similar toEarth's water is much larger than scientists previously thought - it contains a lot of sodium chloride. The discovery also increases the likelihood that life exists within it.

It was previously reported that NASA is consideringthe possibility of sending a drilling rig with a nuclear reactor to Jupiter's satellite Europa. The research apparatus will study the subglacial ocean of the exoplanet for the presence of life in it.
