<div class="text-justify">In an exciting discovery, researchers at the Los Alamos National Laboratory in the US have suggested that Mars may have been a habitable planet in ancient times. </div><P/>
<div class="text-justify">According to a statement issued by the agency, this finding is based on analysis of the latest samples collected by the Curiosity rover.</div><P/>
<div class="text-justify">The ChemCam instrument onboard Curiosity has detected elevated levels of manganese in lake-bottom rocks in the Murray Formation, located in Mars' ancient Gale Crater. </div><P/>
<div class="text-justify">This discovery reveals intriguing facts about the chemical composition of Mars in the past and raises the possibility that the planet may have harboured life.</div><P/>
<div class="text-justify">The study has revealed that the coarse-grained rocks show a remarkable enrichment of up to 45 times in manganese and up to 1.5 times in iron compared to the average chemical composition of the fine-grained rocks of the formation. </div><P/>
<div class="text-justify">The authors of the study suggest that these deposits could have formed in a river, a delta or near the shore of an ancient lake.</div><P/>

<div class="text-justify">The discovery of high concentrations of manganese oxide in a coastal deposit on Mars has surprised scientists. </div><P/>
<div class="text-justify">Patrick Gasda, the scientist who led the research recently published in the Journal of Geophysical Research, explained: ‘It is difficult for manganese oxide to form on the surface of Mars, so we didn't expect to find it in such high concentrations in a coastal deposit’.</div><P/>
<div class="text-justify">These findings suggest that Mars may have had the right conditions to support life in the past. </div><P/>
<div class="text-justify">The enrichment of manganese and iron in the rocks of ancient Gale Crater indicates the presence of chemical and geological processes that could have supported the existence of living organisms.</div><P/>
<div class="text-justify">This discovery raises exciting questions about the history of Mars and its potential for life. </div><P/>

<div class="text-justify">If Mars was once a habitable planet, what happened to make it the inhospitable place we know today? What factors led to the disappearance of conditions conducive to life?</div><P/>
<div class="text-justify">Researchers at Los Alamos National Laboratory continue to analyse samples collected by the Curiosity rover, looking for more clues about the history of Mars and its potentially habitable past. </div><P/>
<div class="text-justify">These new findings are a reminder of the importance of space exploration and the study of other planets to better understand our own origin and place in the vast universe.</div><P/>
