<p>The European Space Agency's ExoMars Trace Gas Orbiter has captured the intriguing but spooky 'smiley face'-shaped salt deposit on Mars, which has left the netizens stunned.&nbsp;</p>

<p>According to the scientists, this salt deposit may have concealed the remnants of the last surviving life forms on Mars.</p>

<p>Mars had vast lakes and rivers billions of years ago, which disappeared during a catastrophic global freeze.&nbsp;</p>

<p>The researchers have proposed that this emoticon-shaped salt deposit may be harbouring hardy microbes.</p>

<p>Explaining the salt deposits on Mars, planetary scientist at the University of Bern in Switzerland Valentin Bickel said, ''A cold era began when Mars lost its magnetic field and could no longer hold its atmosphere, leading to water evaporating, freezing, or becoming trapped within the surface. As the water disappeared over time, it left mineral fingerprints on the surface. Very salty waters could have become a haven for life, a beacon for habitable places on Mars. High concentrations of salt allow water to remain liquid at temperatures as low as minus 40 degrees Celsius."</p>
