The mysterious red streaks that cross its surface moon of Jupiter, Europamay be the result of a recently discovered type of salty ice.

Europe has long attracted the interest of scientists because of it “underground” ocean which hides under the thick shell of ice on its surface.

A large amount of water is released from cracks which exist in ice shell of Europaeffectively freeing the content of the ocean, which the moon has, towards space.

Such discoveries as in Europe are the best proof of life outside Earthaccording to scientists.

The red streaks on the surface of Europa, believed to be one frozen mixture of water and saltsseemed unusual because it didn’t match any known substance on Earth.

Scientists found in 2019 that the yellow parts of Europa’s surface were caused by in the presence of sodium chloride – better known as table salt.

To unlock more information about Europa, which will be visited by the European Space Agency’s JUICE mission (short for Jupiter Icy Moons Explorer) and NASA’s Europa Clipper mission within the next two years, scientists worked to recreate the conditions of the moon in a laboratory.


The research team found that the combination water, salt, low temperatures and high pressure resulted in a new type of solid crystal – and this substance could exist on Europa’s surface and at the bottom of its hidden ocean.

It is rare these days to have fundamental discoveries in science. Salt and water are well known in earth conditions. But beyond that, we are completely in the dark. We need to repeat all the fundamental mineralogical science that people did in the 1800s, but at high pressure and low temperature. It’s an exciting time for ussaid the study’s lead author Baptiste Journaux, assistant professor of Earth and Space Sciences at University of Washington.
